$$- 6 ( 16 - 5 ) \times 7 - 21 \div 13$$

Evaluate

$$-\frac{6027}{13}\approx -463.615384615$$

Solution Steps

Subtract 5 from 16 to get 11.

$$-6\times 11\times 7-\frac{21}{13}$$

Multiply -6 and 11 to get -66.

$$-66\times 7-\frac{21}{13}$$

Multiply -66 and 7 to get -462.

$$-462-\frac{21}{13}$$

Convert -462 to fraction -\frac{6006}{13}.

$$-\frac{6006}{13}-\frac{21}{13}$$

Since -\frac{6006}{13} and \frac{21}{13} have the same denominator, subtract them by subtracting their numerators.

$$\frac{-6006-21}{13}$$

Subtract 21 from -6006 to get -6027.

$$-\frac{6027}{13}$$

Factor

$$-\frac{6027}{13} = -463\frac{8}{13} = -463.61538461538464$$
