Solve 1/1+3/5-8/4

$$\frac{ 1 }{ 1 } + \frac{ 3 }{ 5 } - \frac{ 8 }{ 4 }$$

Evaluate

$$-\frac{2}{5}=-0.4$$

Solution Steps

Divide 1 by 1 to get 1.

$$1+\frac{3}{5}-\frac{8}{4}$$

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

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

Since \frac{5}{5} and \frac{3}{5} have the same denominator, add them by adding their numerators.

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

Add 5 and 3 to get 8.

$$\frac{8}{5}-\frac{8}{4}$$

Divide 8 by 4 to get 2.

$$\frac{8}{5}-2$$

Convert 2 to fraction \frac{10}{5}.

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

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

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

Subtract 10 from 8 to get -2.

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

Factor

$$-\frac{2}{5} = -0.4$$
