Solve -21/3*(+12/7)-(-3)=

$$- 2 \frac { 1 } { 3 } \times ( + 1 \frac { 2 } { 7 } ) - ( - 3 ) =$$

Evaluate

$$0$$

Solution Steps

Multiply 2 and 3 to get 6.

$$\left(-\frac{6+1}{3}\right)\times \frac{1\times 7+2}{7}-\left(-3\right)$$

Add 6 and 1 to get 7.

$$-\frac{7}{3}\times \frac{7+2}{7}-\left(-3\right)$$

Add 7 and 2 to get 9.

$$-\frac{7}{3}\times \frac{9}{7}-\left(-3\right)$$

Multiply -\frac{7}{3} times \frac{9}{7} by multiplying numerator times numerator and denominator times denominator.

$$\frac{-7\times 9}{3\times 7}-\left(-3\right)$$

Do the multiplications in the fraction \frac{-7\times 9}{3\times 7}.

$$\frac{-63}{21}-\left(-3\right)$$

Divide -63 by 21 to get -3.

$$-3-\left(-3\right)$$

The opposite of -3 is 3.

$$-3+3$$

Add -3 and 3 to get 0.

$$0$$

Factor

$$0$$
