Solve 21/3div(-31/3)

$$2 \frac { 1 } { 3 } \div ( - 3 \frac { 1 } { 3 } )$$

Evaluate

$$-\frac{7}{10}=-0.7$$

Solution Steps

Multiply 2 and 3 to get 6.

$$\frac{\frac{6+1}{3}}{-\frac{3\times 3+1}{3}}$$

Add 6 and 1 to get 7.

$$\frac{\frac{7}{3}}{-\frac{3\times 3+1}{3}}$$

Multiply 3 and 3 to get 9.

$$\frac{\frac{7}{3}}{-\frac{9+1}{3}}$$

Add 9 and 1 to get 10.

$$\frac{\frac{7}{3}}{-\frac{10}{3}}$$

Divide \frac{7}{3} by -\frac{10}{3} by multiplying \frac{7}{3} by the reciprocal of -\frac{10}{3}.

$$\frac{7}{3}\left(-\frac{3}{10}\right)$$

Multiply \frac{7}{3} times -\frac{3}{10} by multiplying numerator times numerator and denominator times denominator.

$$\frac{7\left(-3\right)}{3\times 10}$$

Do the multiplications in the fraction \frac{7\left(-3\right)}{3\times 10}.

$$\frac{-21}{30}$$

Reduce the fraction \frac{-21}{30} to lowest terms by extracting and canceling out 3.

$$-\frac{7}{10}$$

Factor

$$-\frac{7}{10} = -0.7$$
