### Simplification of Numerical Expressions with Decimal Numbers Problems

Know more about numerical expressions involving decimal numbers with some examples.

**Example 1. **

Simplify the numerical expression involving decimal 0.5 + 2 Ã— 1.2 Ã· 0.3 – 0.1

**Solution:**

First step : divide 1.2 Ã· 0.3 = 4

Second step : multiply 2 Ã— 4 = 8

Third step : subtract 8 – 0.1 = 7.9

Fourth step : add 7.9 + 0.5 = 8.4

Therefore 0.5 + 2 Ã— 1.2 Ã· 0.3 – 0.1 = 8.4

**Example 2.**

Simplify the numerical expression involving decimal 0.64 Ã· 2.5 + 1.4 Ã— 1.5 – 1.3

**Solution:**

First step : divide 0.64 Ã· 2.5 = 0.256

Second step : multiply 1.4 Ã— 1.5 = 2.1

Third step : subtract 2.1 – 1.3 = 0.8

Fourth step : rearrange the equation 0.256 + 0.8 = 0.32

Therefore 0.64 Ã· 2.5 + 1.4 Ã— 1.5 – 1.3 = 0.32

**Example 3.**

Simplify the numerical expression involving decimal 3 – 1.5 Ã· 6 Ã— 0.6 + 2

**Solution:**

First step : divide 1.5 Ã· 6 = 0.25

Second step : multiply 0.25 Ã— 0.6 = 0.15

Third step : subtract 3 – 0.25 = 2.75

Fourth step : add 0.15 + 2 = 2.15

Therefore 3 – 1.5 Ã· 6 Ã— 0.6 + 2 = 2.15

**Example 4.**

Simplify the numerical expression involving decimal 0.5 + 4 Ã— 1.24 Ã· 0.8 – 0.7

**Solution:**

First step : divide 1.24 Ã· 0.8 = 1.55

Second step : multiply 4 Ã— 1.55 = 6.2

Third step : subtract 6.2 – 0.7 = 5.5

Fourth step : add 0.5 + 5.5 = 6

Therefore 0.5 + 4 Ã— 1.24 Ã· 0.8 – 0.7 = 6

**Example 5.**

Simplify the numerical expression involving decimal 4.82 – 2.4 Ã· 7 Ã— 0.8 + 8

**Solution:**

First step : divide 2.4 Ã· 7 = 0.34

Second step : multiply 0.34 Ã— 0.8 = 0.272

Third step : subtract 4.82 + 0.272 = 4.548

Fourth step : add 4.548 + 8 = 12.54

Therefore 4.82 – 2.4 Ã· 7 Ã— 0.8 + 8 = 12.54
