Solve 318/20+25/20=

$$3 \frac { 18 } { 20 } + 2 \frac { 5 } { 20 } =$$

Evaluate

$$\frac{123}{20}=6.15$$

Solution Steps

Multiply 3 and 20 to get 60.

$$\frac{60+18}{20}+\frac{2\times 20+5}{20}$$

Add 60 and 18 to get 78.

$$\frac{78}{20}+\frac{2\times 20+5}{20}$$

Reduce the fraction \frac{78}{20} to lowest terms by extracting and canceling out 2.

$$\frac{39}{10}+\frac{2\times 20+5}{20}$$

Multiply 2 and 20 to get 40.

$$\frac{39}{10}+\frac{40+5}{20}$$

Add 40 and 5 to get 45.

$$\frac{39}{10}+\frac{45}{20}$$

Reduce the fraction \frac{45}{20} to lowest terms by extracting and canceling out 5.

$$\frac{39}{10}+\frac{9}{4}$$

Least common multiple of 10 and 4 is 20. Convert \frac{39}{10} and \frac{9}{4} to fractions with denominator 20.

$$\frac{78}{20}+\frac{45}{20}$$

Since \frac{78}{20} and \frac{45}{20} have the same denominator, add them by adding their numerators.

$$\frac{78+45}{20}$$

Add 78 and 45 to get 123.

$$\frac{123}{20}$$

Factor

$$\frac{3 \cdot 41}{2 ^ {2} \cdot 5} = 6\frac{3}{20} = 6.15$$
