$$[ \frac { 1 } { 5 } + \frac { 3 } { 6 } ]$$

Evaluate

$$\frac{7}{10}=0.7$$

Solution Steps

Reduce the fraction \frac{3}{6} to lowest terms by extracting and canceling out 3.

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

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

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

Since \frac{2}{10} and \frac{5}{10} have the same denominator, add them by adding their numerators.

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

Add 2 and 5 to get 7.

$$\frac{7}{10}$$

Factor
