## Simplification of Numerical Expressions

A numerical expression is a mathematical statement with different fundamental operations such as addition, subtraction, multiplication, and division. To simplify the numerical expression with different operations we use brackets to make the calculation easy. There is a trick to remember the concept of numerical expressions i.e, BODMAS Rule.

B – Brackets

O – of means

D – Division

M – Multiplication

A – Addition

S – Subtraction

### Evaluating Numerical Expressions Involving Fractional Numbers Questions

The concept of Numerical Expressions Involving Fractional Numbers is explained in detail with examples from the below section.

**Example 1. **

Simplify the numerical expression involving fractional numbers of equation is 19/4 + 5/2 ÷ 7/2 – 3/2

**Solution:**

Given that,

19/4 + 5/2 ÷ 7/2 – 3/2

=19/4 + 5/2 × 7/2 – 3/2( first step: divide 5/2 × 7/2 = 5/7)

=19/4 + 5/7 – 3/2( second step: add 19/4 + 5/7 = 65/28)

=65/28 – 3/2( third step: subtract 65/28 – 3/2 = 23/28

= 23/28

Therefore 19/4 + 5/2 ÷ 7/2 – 3/2 = 23/28

**Example 2. **

Simplify the numerical expression involving fractional numbers of equation is 7/2 + 12/7 × 2/3 – 1/4 ÷ 4

**Solution:**

7/2 + 12/7 × 2/3 – 1/4 ÷ 4

7/2 + 12/7 × 2/3 – 1/4 × 1/4(first step: divide 1/4 by 4 = 1/4 × 1/4)

= 7/2 + 12/7 × 2/3 – 1/16(second step: 1/4 × 1/4 = 1/16)

= 7/2 + 8/7 – 1/16( third step: multiply 12/7 × 2/3 = 8/7)

= 4 – 1/6( fourth step: add 7/2 + 8/7 = 4)

= 23/6( fiveth step: subtract 4 – 1/6 = 23/6)

Therefore 7/2 + 12/7 × 2/3 – 1/4 ÷ 4 = 23/6.

**Example 3.**

Simplify the numerical expression involving fractional numbers of equation is 7/3 – {5/2 ÷ (9/5 – 1/2)}

**Solution:**

Given that,

7/3 – {5/2 ÷( 9/5 – 1/2)}

Subtract 9/5 – 1/2 = 13/10

=7/3 – { 5/2 ÷ 13/10}

Divide 5/2 ÷ 13/10 = 1/12

=7/3 – 1/12

Subtract 7/3 – 1/12 = 9/4

=9/4

Therefore 7/4 – {5/2 ÷ (9/5 – 1/2)} = 9/4

**Example 4. **

Simplify the numerical expression involving fractional numbers of equation is 11/7 + 25/8 ÷ 5/4 – 7/3

**Solution:**

Given that,

11/7 + 25/8 ÷ 5/4 – 7/3

=11/7 + 25/8 × 5/4 – 7/3( first step: multiply 25/8 × 5/4 = 5/2)

= 11/7 + 5/2 – 7/3(second step: add 11/7 + 5/2 = 57/14)

= 57/14 – 7/3( third step: subtract 57/14 – 7/3 =74/42)

= 74/42

Therefore 11/7 + 25/8 ÷ 5/4 – 7/3 = 74/42

**Example 5.**

Simplify the numerical expression involving fractional numbers of equation is 7/4 + 21/8 × 1/3 – 1/2 ÷ 2

**Solution:**

Given that,

7/4 + 21/8 × 1/3 – 1/2 ÷ 2(divide 1/2 by 2 = 1/2 × 1/2)

= 7/4 + 21/8 × 1/3 – 1/2 × 1/2( multiply 1/2 × 1/2 = 1/4

= 7/4 + 21/8 × 1/3 – 1/4( multiply 21/8 × 1/3 = 21/32)

= 7/4 + 21/32 – 1/4( add 7/4 + 21/32 = 77/32)

= 77/32 – 1/4( subtract 77/32 – 1/4 = 69/32)

= 69/32

Therefore 7/4 + 21/8 × 1/3 – 1/2 ÷ 2 = 69/32.
