Understanding Division of Whole Numbers Within Parentheses Involving Division

Complete explanation with examples

The division of whole numbers within parentheses where there is a division refers to the situation in which we must carry out the mathematical operation of dividing a whole number by the result of dividing two elements, that is, by their quotient.

For example:

24:(6:2)24 : (6 : 2)

There are two ways to solve this type of exercises.

The first one will be to open the parentheses and extract the numbers that were inside them.

That is, in our example:

24:(6:2)=24 : (6 : 2) =

24:6×2= 24:6\times2=

4×2=8 4\times2=8

Examples with solutions for Division of Whole Numbers Within Parentheses Involving Division

Step-by-step solutions included
Exercise #1

13−(7+4)= 13-(7+4)=

Step-by-Step Solution

According to the order of operations, we first solve the exercise within parentheses:

7+4=11 7+4=11

Now we subtract:

13−11=2 13-11=2

Answer:

2 2

Exercise #2

2−(1+1)= 2-(1+1)=

Step-by-Step Solution

To solve the expression 2−(1+1) 2 - (1 + 1) , follow these steps:

  • First, evaluate the expression inside the parentheses: 1+1 1 + 1 .
  • This gives 2 2 .
  • Now replace the parentheses with this result, transforming the expression to 2−2 2 - 2 .
  • The result of 2−2 2 - 2 is 0 0 .

Therefore, the solution to the expression is 0 0 .

Answer:

0

Exercise #3

100−(30−21)= 100-(30-21)=

Step-by-Step Solution

According to the order of operations, we first solve the exercise within parentheses:

30−21=9 30-21=9

Now we obtain:

100−9=91 100-9=91

Answer:

91 91

Video Solution
Exercise #4

100−(5+55)= 100-(5+55)=

Step-by-Step Solution

To solve this problem, we'll follow these steps:

  • Step 1: Calculate the sum inside the parentheses.
  • Step 2: Subtract the result of the sum from 100.

Now, let's work through each step:
Step 1: Calculate 5+555 + 55, which gives 6060.
Step 2: Perform the subtraction 100−60100 - 60, which equals 4040.

Therefore, the solution to the problem is 40 40 .

Answer:

40

Exercise #5

12:(2×2)= 12:(2\times2)=

Step-by-Step Solution

According to the order of operations, we first solve the exercise within parentheses:

2×2=4 2\times2=4

Now we divide:

12:4=3 12:4=3

Answer:

3 3

Frequently Asked Questions

How do you solve division problems with parentheses?

+
There are two main methods: 1) Use the formula a:(b:c) = a:b×c to remove parentheses, or 2) Follow order of operations by solving the expression inside parentheses first. Both methods will give you the same correct answer.

What is the rule for a:(b:c) in division?

+
The rule is a:(b:c) = a:b×c. This means you can rewrite the division by a quotient as multiplication. For example, 24:(6:2) becomes 24:6×2 = 4×2 = 8.

Why do we get the same answer using different methods for division with parentheses?

+
Both methods follow mathematical principles correctly. The order of operations method solves step-by-step, while the formula method uses algebraic properties to transform the expression. They're mathematically equivalent approaches.

How do you handle nested parentheses in division problems?

+
Start from the innermost parentheses and work outward. Convert divisions to fractions when helpful, then multiply step by step. For example, in 10:(2:(15:7)), first solve 15:7, then 2:(15:7), finally 10 divided by that result.

What are common mistakes when dividing with parentheses?

+
Common errors include: • Ignoring order of operations • Forgetting to convert division to multiplication correctly • Making arithmetic errors in fraction simplification • Not starting with innermost parentheses in nested expressions

How do you convert division expressions to fractions?

+
Replace the division symbol with a fraction bar. For example, (6:2) becomes 6/2, and 24:(6:2) becomes 24÷(6/2) = 24×(2/6). This often makes calculations clearer and easier to follow.

When should I use the formula method vs order of operations?

+
Use order of operations for simple expressions with whole numbers. Use the formula method (a:(b:c) = a:b×c) when working with variables, fractions, or when you want to see the algebraic structure more clearly.

How do you simplify final answers in division with parentheses problems?

+
Always reduce fractions to lowest terms, convert improper fractions to mixed numbers when appropriate, and factor out common terms in algebraic expressions. For example, 75/7 becomes 10 5/7 as a mixed number.
