Solve 21/3+2/5

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

Evaluate

$$\frac{41}{15}\approx 2.733333333$$

Solution Steps

Multiply 2 and 3 to get 6.

$$\frac{6+1}{3}+\frac{2}{5}$$

Add 6 and 1 to get 7.

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

Least common multiple of 3 and 5 is 15. Convert \frac{7}{3} and \frac{2}{5} to fractions with denominator 15.

$$\frac{35}{15}+\frac{6}{15}$$
