Solve 57/8-23/8=

$$5 \frac { 7 } { 8 } - 2 \frac { 3 } { 8 } =$$

Evaluate

$$\frac{7}{2}=3.5$$

Solution Steps

Multiply 5 and 8 to get 40.

$$\frac{40+7}{8}-\frac{2\times 8+3}{8}$$

Add 40 and 7 to get 47.

$$\frac{47}{8}-\frac{2\times 8+3}{8}$$

Multiply 2 and 8 to get 16.

$$\frac{47}{8}-\frac{16+3}{8}$$

Add 16 and 3 to get 19.

$$\frac{47}{8}-\frac{19}{8}$$

Since \frac{47}{8} and \frac{19}{8} have the same denominator, subtract them by subtracting their numerators.

$$\frac{47-19}{8}$$

Subtract 19 from 47 to get 28.

$$\frac{28}{8}$$

Reduce the fraction \frac{28}{8} to lowest terms by extracting and canceling out 4.

$$\frac{7}{2}$$

Factor

$$\frac{7}{2} = 3\frac{1}{2} = 3.5$$
