Solve 91/8-37/8

$$9 \frac { 1 } { 8 } - 3 \frac { 7 } { 8 }$$

Evaluate

$$\frac{21}{4}=5.25$$

Solution Steps

Multiply 9 and 8 to get 72.

$$\frac{72+1}{8}-\frac{3\times 8+7}{8}$$

Add 72 and 1 to get 73.

$$\frac{73}{8}-\frac{3\times 8+7}{8}$$

Multiply 3 and 8 to get 24.

$$\frac{73}{8}-\frac{24+7}{8}$$

Add 24 and 7 to get 31.

$$\frac{73}{8}-\frac{31}{8}$$

Since \frac{73}{8} and \frac{31}{8} have the same denominator, subtract them by subtracting their numerators.

$$\frac{73-31}{8}$$

Subtract 31 from 73 to get 42.

$$\frac{42}{8}$$

Reduce the fraction \frac{42}{8} to lowest terms by extracting and canceling out 2.

$$\frac{21}{4}$$

Factor

$$\frac{3 \cdot 7}{2 ^ {2}} = 5\frac{1}{4} = 5.25$$
