Remainders and Mixed Numbers

In this article, we will learn about the remainder in a mixed number as well as how to identify it effortlessly!
Let's begin by reviewing mixed fractions.

Reminder –
A mixed number is a number that consists of two parts – a whole number and a fraction
Hence its name, it mixes both a whole number and a fraction.

For example:
5235 \frac{2}{3}

In this mixed number there are 55 wholes and a fraction of 232 \over 3

How can we identify the remainder in a mixed number?

Easy!
The remainder is always the non-whole part!
This means that the remainder is always the fractional part in a mixed number.

Let's look at an example:
Determine the fractional part in 4144 \frac{1}{4}?
The answer is of course 141 \over 4

Do you want to understand why the remainder is always the fractional part? Read the following explanation!
A remainder can be defined as the part that's left over when we perform a division operation and the number that we divided doesn't divide evenly.
For example - if I have 44 notebooks and I have 33 children it will result in a remainder due to the fact that each child will get one notebook and one notebook will be left over. I'll need to divide the spare notebook into 33 equal parts.
The equal part that will be shared among everyone will make up remainder given that it's the part that doesn't divide evenly.
However, if for example I had 66 notebooks and 33 children, I could give each child 22 notebooks and I wouldn't have a remainder.
Therefore, a remainder is always that part that doesn't divide evenly and needs to be divided equally among everyone!

Advanced Exercise -
Anat and Batya are sisters in 3rd grade. Anat brought 77 fruits to the end-of-year party and Batya brought 55 fruits to the end-of-year party.
There were 33 children at the party.
Anat and Batya's mom asked them to distribute the fruits equally among the children without remainders - meaning to bring the remainder home (fruit that needs to be cut will not be divided and will be returned home) because she wants to make a fruit salad from the remaining fruits.
How many fruits did Anat return and how many fruits did Batya return?

Solution -
In this question we were asked to understand what would be the remainder for Anat and what would be the remainder for Batya.
Let's start with Anat - she has 77 fruits and she needs to divide them without a remainder.

73=213\frac {7}{3} = 2\frac{1}{3}

We can deduce that she can distribute 22 fruits equally to each child and will be left with 11 fruit that she needs to divide by 33 - meaning she distributes 66 fruits and takes 11 fruit back home.
Let's move to Batya - she has 55 fruits and there are 33 children

53=123\frac{5}{3} = 1\frac{2}{3}

She can only distribute one fruit equally to each person leaving her with 22 fruits that she will need to divide between everyone, which means she distributes 33 fruits in total and returns 22 home.

In total, Anat and Batya returned 33 fruits.

Sometimes you will encounter an improper fraction, and it would be beneficial to convert it to a mixed number to immediately identify the remainder.
When in an improper fraction the numerator equals the denominator - there is no remainder, the number is whole.
In an improper fraction where the numerator is greater than the denominator - we can easily convert it to a mixed number in the following way:
We ask how many times does the denominator fit into the numerator?
This will be our whole number.
What remains will be the numerator in the fraction part of the mixed number.
For example, to convert the improper fraction 525\over2 to a mixed number,
We ask - how many times does 22 go into 55?
The answer is 22 - this will be our whole number.
What remains - 11, will be the numerator in the mixed number. Therefore we obtain the following:

52=212\frac{5}{2} = 2\frac{1}{2}

Converting an improper fraction to a mixed number and finding the remainder exercise -
Bar brought 55 strawberries to class and wanted to divide them equally between 44 friends.
How did Bar divide the strawberries equally and what is the remainder?

Solution:

Bar wanted to divide 55 by 44 which means 545 \over4.
We learned that if we convert an improper fraction to a mixed number, we can immediately see the remainder -
So we'll convert 545 \over4 to a mixed number and obtain 1141 \frac{1}{4}.
This means Bar first gave one whole strawberry to each of the 11 of four friends, and then she had one strawberry left which she divided into 44 equal parts between all of them.
The remaining part that was divided between everyone is 141\over 4 and this can also be seen from the appearance of the mixed number.

Examples with solutions for Mixed Numbers and Fractions Greater than 1

Exercise #1

Write the fraction as a mixed number:

107= \frac{10}{7}=

Video Solution

Step-by-Step Solution

To solve the problem, we will convert the given improper fraction 107\frac{10}{7} to a mixed number by dividing the numerator by the denominator.

  • Step 1: Divide the numerator (10) by the denominator (7). This gives a quotient and a remainder.

  • Step 2: Calculating 10Γ·710 \div 7 gives a quotient of 1 because 7 goes into 10 once.

  • Step 3: Multiply the quotient by the divisor (1Γ—7=7 1 \times 7 = 7 ).

  • Step 4: Subtract the product obtained in step 3 from the original numerator to find the remainder: 10βˆ’7=310 - 7 = 3.

  • Step 5: Compose the mixed number using the quotient as the whole number and the remainder over the divisor as the fraction part: 37\frac{3}{7}.

Thus, the mixed number representation of 107\frac{10}{7} is 137\mathbf{1\frac{3}{7}}.

Answer

137 1\frac{3}{7}

Exercise #2

Write the fraction as a mixed number:

128= \frac{12}{8}=

Video Solution

Step-by-Step Solution

To solve this problem, we need to convert the improper fraction 128 \frac{12}{8} into a mixed number.

Here's how we'll do it:

  • The first step is to divide the numerator by the denominator: 12Γ·8 12 \div 8 .
  • This division gives us a quotient of 1 and a remainder of 4.
  • The quotient, 1, becomes the whole number part of our mixed number.
  • The remainder is used as the new numerator over the original denominator to form the fractional part: 48\frac{4}{8}.
  • The mixed number is thus 148 1\frac{4}{8} .
  • Finally, since 48\frac{4}{8} can be simplified, we reduce it to 12\frac{1}{2}.

Thus, the mixed number representation is correctly simplified as 112 1\frac{1}{2} .

However, when selecting from the given choices, the correct choice based on the options provided is 148 1\frac{4}{8} (Choice 4), which matches the unsimplified form.

Therefore, the solution to the problem is 148 1\frac{4}{8} .

Answer

148 1\frac{4}{8}

Exercise #3

Write the fraction as a mixed number:

139= \frac{13}{9}=

Video Solution

Step-by-Step Solution

To convert the improper fraction 139\frac{13}{9} into a mixed number, we follow these steps:

  • Step 1: Perform the division of the numerator by the denominator. Divide 13 by 9.
  • Step 2: Determine the whole number part by using the quotient of the division.
  • Step 3: Find the remainder to establish the fractional part.
  • Step 4: Write the mixed number using the whole number from Step 2 and the fractional part formed by the remainder and original denominator.

Let's carry out these steps in detail:

Divide 13 by 9:

13Γ·9=1 13 \div 9 = 1 with a remainder of 4 4 .

This division tells us that 9 fits into 13 a total of 1 time, with a remainder of 4.

The whole number part of our mixed number is therefore 1, and the remainder 4 forms the numerator of our fractional part over the original denominator, which is 9.

So, the fractional part is 49\frac{4}{9}.

Therefore, the improper fraction 139\frac{13}{9} as a mixed number is 149\mathbf{1\frac{4}{9}}.

Answer

149 1\frac{4}{9}
