Solve -1/5+3/2-0.3

$$- \frac { 1 } { 5 } + \frac { 3 } { 2 } - 0.3$$

Evaluate

$$1$$

Solution Steps

Least common multiple of 5 and 2 is 10. Convert -\frac{1}{5} and \frac{3}{2} to fractions with denominator 10.

$$-\frac{2}{10}+\frac{15}{10}-0.3$$

Since -\frac{2}{10} and \frac{15}{10} have the same denominator, add them by adding their numerators.

$$\frac{-2+15}{10}-0.3$$

Add -2 and 15 to get 13.

$$\frac{13}{10}-0.3$$

Convert decimal number 0.3 to fraction \frac{3}{10}.

$$\frac{13}{10}-\frac{3}{10}$$

Since \frac{13}{10} and \frac{3}{10} have the same denominator, subtract them by subtracting their numerators.

$$\frac{13-3}{10}$$

Subtract 3 from 13 to get 10.

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

Divide 10 by 10 to get 1.

$$1$$

Factor
