Solve 42/5-11/2*2

$$4 \frac { 2 } { 5 } - 1 \frac { 1 } { 2 } \times 2$$

Evaluate

$$\frac{7}{5}=1.4$$

Solution Steps

Multiply 4 and 5 to get 20.

$$\frac{20+2}{5}-\frac{1\times 2+1}{2}\times 2$$

Add 20 and 2 to get 22.

$$\frac{22}{5}-\frac{1\times 2+1}{2}\times 2$$

Multiply 1 and 2 to get 2.

$$\frac{22}{5}-\frac{2+1}{2}\times 2$$

Add 2 and 1 to get 3.

$$\frac{22}{5}-\frac{3}{2}\times 2$$

Cancel out 2 and 2.

$$\frac{22}{5}-3$$

Convert 3 to fraction \frac{15}{5}.

$$\frac{22}{5}-\frac{15}{5}$$

Since \frac{22}{5} and \frac{15}{5} have the same denominator, subtract them by subtracting their numerators.

$$\frac{22-15}{5}$$

Subtract 15 from 22 to get 7.

$$\frac{7}{5}$$

Factor

$$\frac{7}{5} = 1\frac{2}{5} = 1.4$$
