Solve 65/8div-1/2=

$$6 \frac { 5 } { 8 } \div \frac { - 1 } { 2 } =$$

Evaluate

$$-\frac{53}{4}=-13.25$$

Solution Steps

Divide \frac{6\times 8+5}{8} by \frac{-1}{2} by multiplying \frac{6\times 8+5}{8} by the reciprocal of \frac{-1}{2}.

$$\frac{\left(6\times 8+5\right)\times 2}{8\left(-1\right)}$$

Cancel out 2 in both numerator and denominator.

$$\frac{5+6\times 8}{-4}$$

Multiply 6 and 8 to get 48.

$$\frac{5+48}{-4}$$
