Solution Steps

Reduce the fraction \frac{54}{20} to lowest terms by extracting and canceling out 2.

$$\frac{27}{10}+\frac{140}{20}+\frac{68}{20}$$

Divide 140 by 20 to get 7.

$$\frac{27}{10}+7+\frac{68}{20}$$

Convert 7 to fraction \frac{70}{10}.

$$\frac{27}{10}+\frac{70}{10}+\frac{68}{20}$$

Since \frac{27}{10} and \frac{70}{10} have the same denominator, add them by adding their numerators.

$$\frac{27+70}{10}+\frac{68}{20}$$

Add 27 and 70 to get 97.

$$\frac{97}{10}+\frac{68}{20}$$

Reduce the fraction \frac{68}{20} to lowest terms by extracting and canceling out 4.

$$\frac{97}{10}+\frac{17}{5}$$

Least common multiple of 10 and 5 is 10. Convert \frac{97}{10} and \frac{17}{5} to fractions with denominator 10.

$$\frac{97}{10}+\frac{34}{10}$$

Since \frac{97}{10} and \frac{34}{10} have the same denominator, add them by adding their numerators.

$$\frac{97+34}{10}$$

Add 97 and 34 to get 131.

$$\frac{131}{10}$$

Factor

$$\frac{131}{2 \cdot 5} = 13\frac{1}{10} = 13.1$$
