Solve 12/12+6/18+7/9=

$$12 / 12 + 6 / 18 + 7 / 9 =$$

Evaluate

$$\frac{19}{9}\approx 2.111111111$$

Solution Steps

Divide 12 by 12 to get 1.

$$1+\frac{6}{18}+\frac{7}{9}$$

Reduce the fraction \frac{6}{18} to lowest terms by extracting and canceling out 6.

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

Convert 1 to fraction \frac{3}{3}.

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

Since \frac{3}{3} and \frac{1}{3} have the same denominator, add them by adding their numerators.

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

Add 3 and 1 to get 4.

$$\frac{4}{3}+\frac{7}{9}$$

Least common multiple of 3 and 9 is 9. Convert \frac{4}{3} and \frac{7}{9} to fractions with denominator 9.

$$\frac{12}{9}+\frac{7}{9}$$

Since \frac{12}{9} and \frac{7}{9} have the same denominator, add them by adding their numerators.

$$\frac{12+7}{9}$$

Add 12 and 7 to get 19.

$$\frac{19}{9}$$

Factor

$$\frac{19}{3 ^ {2}} = 2\frac{1}{9} = 2.111111111111111$$
