Solve 21/3-(-9)

$$2 \frac { 1 } { 3 } - ( - 9 )$$

Evaluate

$$\frac{34}{3}\approx 11.333333333$$

Solution Steps

Multiply 2 and 3 to get 6.

$$\frac{6+1}{3}-\left(-9\right)$$

Add 6 and 1 to get 7.

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

The opposite of -9 is 9.

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

Convert 9 to fraction \frac{27}{3}.

$$\frac{7}{3}+\frac{27}{3}$$

Since \frac{7}{3} and \frac{27}{3} have the same denominator, add them by adding their numerators.

$$\frac{7+27}{3}$$

Add 7 and 27 to get 34.

$$\frac{34}{3}$$

Factor

$$\frac{2 \cdot 17}{3} = 11\frac{1}{3} = 11.333333333333334$$
