Solve 0,8-0,4/0,3+0,5

$$0,8 - \frac { 0,4 } { 0,3 + 0,5 }$$

Evaluate

$$0,3$$

Solution Steps

Add 0,3 and 0,5 to get 0,8.

$$0,8-\frac{0,4}{0,8}$$

Expand \frac{0,4}{0,8} by multiplying both numerator and the denominator by 10.

$$0,8-\frac{4}{8}$$

Reduce the fraction \frac{4}{8} to lowest terms by extracting and canceling out 4.

$$0,8-\frac{1}{2}$$

Convert decimal number 0,8 to fraction \frac{8}{10}. Reduce the fraction \frac{8}{10} to lowest terms by extracting and canceling out 2.

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

Least common multiple of 5 and 2 is 10. Convert \frac{4}{5} and \frac{1}{2} to fractions with denominator 10.

$$\frac{8}{10}-\frac{5}{10}$$

Since \frac{8}{10} and \frac{5}{10} have the same denominator, subtract them by subtracting their numerators.

$$\frac{8-5}{10}$$

Subtract 5 from 8 to get 3.

$$\frac{3}{10}$$

Factor

$$\frac{3}{2 \cdot 5} = 0.3$$
