Solve 3/8+3/4+1/2

$$\frac { 3 } { 8 } + \frac { 3 } { 4 } + \frac { 1 } { 2 }$$

Evaluate

$$\frac{13}{8}=1.625$$

Solution Steps

Least common multiple of 8 and 4 is 8. Convert \frac{3}{8} and \frac{3}{4} to fractions with denominator 8.

$$\frac{3}{8}+\frac{6}{8}+\frac{1}{2}$$

Since \frac{3}{8} and \frac{6}{8} have the same denominator, add them by adding their numerators.

$$\frac{3+6}{8}+\frac{1}{2}$$

Add 3 and 6 to get 9.

$$\frac{9}{8}+\frac{1}{2}$$

Least common multiple of 8 and 2 is 8. Convert \frac{9}{8} and \frac{1}{2} to fractions with denominator 8.

$$\frac{9}{8}+\frac{4}{8}$$

Since \frac{9}{8} and \frac{4}{8} have the same denominator, add them by adding their numerators.

$$\frac{9+4}{8}$$

Add 9 and 4 to get 13.

$$\frac{13}{8}$$

Factor

$$\frac{13}{2 ^ {3}} = 1\frac{5}{8} = 1.625$$
