Solve -12/3*(-21/2)=

$$- 1 \frac { 2 } { 3 } \cdot ( - 2 \frac { 1 } { 2 } ) =$$

Evaluate

$$\frac{25}{6}\approx 4.166666667$$

Solution Steps

Multiply 1 and 3 to get 3.

$$\left(-\frac{3+2}{3}\right)\left(-\frac{2\times 2+1}{2}\right)$$

Add 3 and 2 to get 5.

$$-\frac{5}{3}\left(-\frac{2\times 2+1}{2}\right)$$

Multiply 2 and 2 to get 4.

$$-\frac{5}{3}\left(-\frac{4+1}{2}\right)$$

Add 4 and 1 to get 5.

$$-\frac{5}{3}\left(-\frac{5}{2}\right)$$

Multiply -\frac{5}{3} times -\frac{5}{2} by multiplying numerator times numerator and denominator times denominator.

$$\frac{-5\left(-5\right)}{3\times 2}$$

Do the multiplications in the fraction \frac{-5\left(-5\right)}{3\times 2}.

$$\frac{25}{6}$$

Factor

$$\frac{5 ^ {2}}{2 \cdot 3} = 4\frac{1}{6} = 4.166666666666667$$
