Solve 0.5+0.2+3/10-2/5

$$0.5+0.2+ \frac{ 3 }{ 10 } - \frac{ 2 }{ 5 }$$

Evaluate

$$0.6$$

Solution Steps

Add 0.5 and 0.2 to get 0.7.

$$0.7+\frac{3}{10}-\frac{2}{5}$$

Convert decimal number 0.7 to fraction \frac{7}{10}.

$$\frac{7}{10}+\frac{3}{10}-\frac{2}{5}$$

Since \frac{7}{10} and \frac{3}{10} have the same denominator, add them by adding their numerators.

$$\frac{7+3}{10}-\frac{2}{5}$$

Add 7 and 3 to get 10.

$$\frac{10}{10}-\frac{2}{5}$$

Divide 10 by 10 to get 1.

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

Convert 1 to fraction \frac{5}{5}.

$$\frac{5}{5}-\frac{2}{5}$$

Since \frac{5}{5} and \frac{2}{5} have the same denominator, subtract them by subtracting their numerators.

$$\frac{5-2}{5}$$

Subtract 2 from 5 to get 3.

$$\frac{3}{5}$$

Factor

$$\frac{3}{5} = 0.6$$
