Solve -111/17*(-123/4)

$$-1 \frac{ 11 }{ 17 } \times (-12 \frac{ 3 }{ 4 } )$$

Evaluate

$$21$$

Solution Steps

Multiply 1 and 17 to get 17.

$$\left(-\frac{17+11}{17}\right)\left(-\frac{12\times 4+3}{4}\right)$$

Add 17 and 11 to get 28.

$$-\frac{28}{17}\left(-\frac{12\times 4+3}{4}\right)$$

Multiply 12 and 4 to get 48.

$$-\frac{28}{17}\left(-\frac{48+3}{4}\right)$$

Add 48 and 3 to get 51.

$$-\frac{28}{17}\left(-\frac{51}{4}\right)$$

Multiply -\frac{28}{17} times -\frac{51}{4} by multiplying numerator times numerator and denominator times denominator.

$$\frac{-28\left(-51\right)}{17\times 4}$$

Do the multiplications in the fraction \frac{-28\left(-51\right)}{17\times 4}.

$$\frac{1428}{68}$$

Divide 1428 by 68 to get 21.

$$21$$

Factor
