Solve -16-3*4+(15-15*3)div65

$$- 16 - 3 \times 4 + ( 15 - 15 \times 3 ) \div 65$$

Evaluate

$$-\frac{370}{13}\approx -28.461538462$$

Solution Steps

Multiply 3 and 4 to get 12.

$$-16-12+\frac{15-15\times 3}{65}$$

Subtract 12 from -16 to get -28.

$$-28+\frac{15-15\times 3}{65}$$

Multiply 15 and 3 to get 45.

$$-28+\frac{15-45}{65}$$

Subtract 45 from 15 to get -30.

$$-28+\frac{-30}{65}$$

Reduce the fraction \frac{-30}{65} to lowest terms by extracting and canceling out 5.

$$-28-\frac{6}{13}$$

Convert -28 to fraction -\frac{364}{13}.

$$-\frac{364}{13}-\frac{6}{13}$$

Since -\frac{364}{13} and \frac{6}{13} have the same denominator, subtract them by subtracting their numerators.

$$\frac{-364-6}{13}$$

Subtract 6 from -364 to get -370.

$$-\frac{370}{13}$$

Factor

$$-\frac{370}{13} = -28\frac{6}{13} = -28.46153846153846$$
