Percentage
A percentage is a number indicated as a fraction of 100. It is a dimensionless number often expressed using the symbol %.
Algebraic Expressions
In mathematics, an algebraic expression consists of constant(s), variable(s), and mathematical operators. It is made up of terms.
Numbers
Numbers are some measures used for counting. They can be compared one with another to know its position in the number line and determine which one is greater or lesser than the other.
Subtraction
Before we begin to understand the subtraction of algebraic expressions, we need to list out a few things that form the basis of algebra.
Addition
Before we begin to understand the addition of algebraic expressions, we need to list out a few things that form the basis of algebra.

Answer to Problem 27PPS

The numerical value of the given expression is 28.

Explanation of Solution

Given:

  7[8(3)÷(15−9)]

Calculation:

The first step asks to solve the brackets first,

Now as there are two types of brackets, first solve the small brackets and then big bracket.

Solving the smaller bracket,

  8(3)=8×3=24

And

  15−9=6

Therefore, the expression finally reduces to

  7[8(3)÷(15−9)]=7[24÷6]

Now, solve the expression inside the big bracket firstly.

That is divide 24 by 6.

  24÷6=4

Thus the main expression reduces to

  7[8(3)÷(15−9)]=7[4]

Since, 7[4]=7×4=28

Therefore the numerical value of the given expression is 28.

  7[8(3)÷(15−9)]=28

Conclusion:

Therefore the numerical value of the given expression is 28.
