Solve -15/8+33/8

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

Evaluate

$$\frac{7}{4}=1.75$$

Solution Steps

Multiply 1 and 8 to get 8.

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

Add 8 and 5 to get 13.

$$-\frac{13}{8}+\frac{3\times 8+3}{8}$$

Multiply 3 and 8 to get 24.

$$-\frac{13}{8}+\frac{24+3}{8}$$

Add 24 and 3 to get 27.

$$-\frac{13}{8}+\frac{27}{8}$$

Since -\frac{13}{8} and \frac{27}{8} have the same denominator, add them by adding their numerators.

$$\frac{-13+27}{8}$$

Add -13 and 27 to get 14.

$$\frac{14}{8}$$

Reduce the fraction \frac{14}{8} to lowest terms by extracting and canceling out 2.

$$\frac{7}{4}$$

Factor

$$\frac{7}{2 ^ {2}} = 1\frac{3}{4} = 1.75$$
