A decimal remainder or decimal fraction is everything that appears to the right of the decimal point.
When the whole number is , the entire number (not just what appears to the right of the decimal point) is the remainder.

A decimal remainder or decimal fraction is everything that appears to the right of the decimal point.
When the whole number is , the entire number (not just what appears to the right of the decimal point) is the remainder.
Determine the number of tenths in the following number:
1.3
A remainder is what is left over after dividing a number that is not evenly divisible by another number, and it is essentially the part that is added to the whole.
Just to clarify - a decimal number with digits after the decimal point represents a non-whole number, meaning a fraction, and therefore can also be called a decimal fraction.
It's really easy!
A decimal number consists of a number, a decimal point, and digits to the right of the decimal point.
Everything that appears to the left of the decimal point is called the whole number.
Everything that appears to the right of the decimal point is called the decimal part.
In other words:
Let's look at an example:
What is the decimal remainder in:
The answer is remainder .
It can also be written as:
Another example:
What is the remainder in the number
The answer is or
Pay attention -
If you see the decimal number and were asked what the remainder is,
you need to remember that everything to the right of the decimal point is the remainder, so in the decimal number
the remainder is and not or
*Even though it's just a digit of , it is significant when dealing with remainders.
Important note:
When we have a decimal number where the whole number part is , meaning it has no whole numbers,
the entire number is actually a remainder, because there are no whole numbers.
For example –
In the number:
The entire number is a remainder.
Think about it this way,
A remainder is obtained when we divide a number by another number and it doesn't divide evenly.
For example, if we divide cake slices among children.
Each child will get one slice and a quarter of a slice.
So the remainder is
But what happens if we want to divide slice between children?
Each child will get half a slice, it's not even whole and therefore the entire half is the remainder.
When will we get a remainder of ?
When there are no digits after the decimal point, we can determine that the remainder is or there is no remainder.
Also, if you encounter only zeros to the right of the decimal point, you can still determine there is no remainder.
Let's look at an example:
What is the remainder in the number ?
There is no remainder.
And now?
?
Still no remainder, remainder .
Special cases:
We said that when a number appears to the right of the decimal point like we can determine that the remainder is or .
But what happens with a decimal number like ?
In this case, the remainder is not but
It's important that we write and then a decimal point to understand the meaning of
Remember - everything that appears to the right of the decimal point is considered a remainder!
And now let's practice:
What is the decimal remainder in ?
Solution:
What is the decimal remainder in ?
Solution:
Since both the remainder is and the whole number is , it is highly recommended to add a decimal point and the digit on the left to emphasize that this is a remainder.
Therefore, the remainder in this number is
What is the remainder in the number ?
Solution: There is no remainder. If there was a decimal point, there would only be to its right.
What is the decimal part in the number 5?
Solution: Note,
if you write it would be a complete mistake since there are several zeros before .
Therefore, the answer is
Determine the number of ones in the following number:
0.4
Determine the number of ones in the following number:
0.07
Determine the number of hundredths in the following number:
0.96
Determine the number of tenths in the following number:
1.3
To solve this problem, we'll follow these steps:
Now, let's work through each step:
Step 1: The problem asks us to count the number of tenths in the decimal number 1.3. This involves understanding the place value of each digit.
Step 2: In the decimal 1.3, the digit '1' represents the whole number and does not contribute to the count of tenths. The digit '3' is in the tenths place.
Step 3: Since the digit '3' is in the tenths place, it denotes 3 tenths or the fraction .
Therefore, the number of tenths in 1.3 is .
3
Determine the number of ones in the following number:
0.4
To solve this problem, we'll follow these steps:
Now, let's work through each step:
Step 1: The number given is 0.4. This number is composed of the digits '0', '.', and '4'.
Step 2: Identify any '1's among these digits. There are no '1's in this sequence of digits.
Step 3: Thus, the count of the digit '1' in the number 0.4 is zero.
Therefore, the number of ones in the number 0.4 is .
0
Determine the number of ones in the following number:
0.07
To solve this problem, we'll examine the given decimal number, , to identify how many '1's it contains.
Let's break down the number :
None of the digits in the number are equal to '1'.
Therefore, the number of ones in is 0.
0
Determine the number of hundredths in the following number:
0.96
To solve this problem, we'll follow these steps:
Now, let's work through each step:
Step 1: Consider the decimal number . In decimal representation, the digit immediately after the decimal point represents tenths, and the digit following that represents hundredths.
Step 2: In the number , the digit is in the tenths place, and the digit is in the hundredths place.
Step 3: Therefore, the number of hundredths in is .
Thus, the solution to the problem is that there are 6 hundredths in the number .
6
Determine the number of ones in the following number:
0.81
To solve this problem, we need to examine the decimal number and count the number of '1's present:
Now, count the number of '1's in :
There is only one '1' in the entire number because it appears only once after the decimal point.
Thus, the total number of ones in is 0, since the task is to count ones in the whole number, and there are no ones in the integer part of , nor in the remaining digits .
Therefore, the solution to the problem is , which corresponds to choice 3.
