Solve 77/8-42/2=

$$7 \frac { 7 } { 8 } - 4 \frac { 2 } { 2 } =$$

Evaluate

$$\frac{23}{8}=2.875$$

Solution Steps

Multiply 7 and 8 to get 56.

$$\frac{56+7}{8}-\frac{4\times 2+2}{2}$$

Add 56 and 7 to get 63.

$$\frac{63}{8}-\frac{4\times 2+2}{2}$$

Multiply 4 and 2 to get 8.

$$\frac{63}{8}-\frac{8+2}{2}$$

Add 8 and 2 to get 10.

$$\frac{63}{8}-\frac{10}{2}$$

Divide 10 by 2 to get 5.

$$\frac{63}{8}-5$$

Convert 5 to fraction \frac{40}{8}.

$$\frac{63}{8}-\frac{40}{8}$$

Since \frac{63}{8} and \frac{40}{8} have the same denominator, subtract them by subtracting their numerators.

$$\frac{63-40}{8}$$

Subtract 40 from 63 to get 23.

$$\frac{23}{8}$$

Factor

$$\frac{23}{2 ^ {3}} = 2\frac{7}{8} = 2.875$$
