Division of Whole Numbers Within Parentheses Involving Division - Examples, Exercises and Solutions

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:

$24 : (6 : 2)$

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:

$24 : (6 : 2) =$

$24:6\times2=$

$4\times2=8$

$7+4=11$

Now we subtract:

$13-11=2$

Answer

$2$

Exercise #5

$38-(18+20)=$

Video Solution

Step-by-Step Solution

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

$18+20=38$

Now, the exercise obtained is:

$38-38=0$

Answer

$0$

examples with solutions for division of whole numbers within parentheses involving division

Exercise #1

$28-(4+9)=$

Video Solution

Step-by-Step Solution

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

$4+9=13$

Now we obtain the exercise:

$28-13=15$

Answer

$15$

Exercise #2

$55-(8+21)=$

Video Solution

Step-by-Step Solution

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

$8+21=29$

Now we obtain the exercise:

$55-29=26$

Answer

$26$

Exercise #3

$37-(4-7)=$

Video Solution

Step-by-Step Solution

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

$4-7=-3$

Now we obtain:

$37-(-3)=$

Remember that the product of a negative and a negative results in a positive, therefore:

$-(-3)=+3$

Now we obtain:

$37+3=40$

Answer

$40$

Exercise #4

$80-(4-12)=$

Video Solution

Step-by-Step Solution

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

$4-12=-8$

Now we obtain the exercise:

$80-(-8)=$

Remember that the product of plus and plus gives us a positive:

$-(-8)=+8$

Now we obtain:

$80+8=88$

Answer

$88$

Exercise #5

$100-(30-21)=$

Video Solution

Step-by-Step Solution
