Solve -12/3+24/9=

$$- 1 \frac { 2 } { 3 } + 2 \frac { 4 } { 9 } =$$

Evaluate

$$\frac{7}{9}\approx 0.777777778$$

Solution Steps

Multiply 1 and 3 to get 3.

$$-\frac{3+2}{3}+\frac{2\times 9+4}{9}$$

Add 3 and 2 to get 5.

$$-\frac{5}{3}+\frac{2\times 9+4}{9}$$

Multiply 2 and 9 to get 18.

$$-\frac{5}{3}+\frac{18+4}{9}$$

Add 18 and 4 to get 22.

$$-\frac{5}{3}+\frac{22}{9}$$

Least common multiple of 3 and 9 is 9. Convert -\frac{5}{3} and \frac{22}{9} to fractions with denominator 9.

$$-\frac{15}{9}+\frac{22}{9}$$

Since -\frac{15}{9} and \frac{22}{9} have the same denominator, add them by adding their numerators.

$$\frac{-15+22}{9}$$

Add -15 and 22 to get 7.

$$\frac{7}{9}$$

Factor

$$\frac{7}{3 ^ {2}} = 0.7777777777777778$$
