Solution Steps

Multiply 7 and 7 to get 49.

$$\frac{49}{8}+2-79$$

Convert 2 to fraction \frac{16}{8}.

$$\frac{49}{8}+\frac{16}{8}-79$$

$$\frac{49+16}{8}-79$$

Add 49 and 16 to get 65.

$$\frac{65}{8}-79$$

Convert 79 to fraction \frac{632}{8}.

$$\frac{65}{8}-\frac{632}{8}$$

Since \frac{65}{8} and \frac{632}{8} have the same denominator, subtract them by subtracting their numerators.

$$\frac{65-632}{8}$$

Subtract 632 from 65 to get -567.

$$-\frac{567}{8}$$

Factor

$$-\frac{567}{8} = -70\frac{7}{8} = -70.875$$
