Solve (1+1/10+3/20)

$$( 1 + \frac { 1 } { 10 } + \frac { 3 } { 20 } )$$

Evaluate

$$\frac{5}{4}=1.25$$

Solution Steps

Convert 1 to fraction \frac{10}{10}.

$$\frac{10}{10}+\frac{1}{10}+\frac{3}{20}$$

Since \frac{10}{10} and \frac{1}{10} have the same denominator, add them by adding their numerators.

$$\frac{10+1}{10}+\frac{3}{20}$$

Add 10 and 1 to get 11.

$$\frac{11}{10}+\frac{3}{20}$$

Least common multiple of 10 and 20 is 20. Convert \frac{11}{10} and \frac{3}{20} to fractions with denominator 20.

$$\frac{22}{20}+\frac{3}{20}$$

Since \frac{22}{20} and \frac{3}{20} have the same denominator, add them by adding their numerators.

$$\frac{22+3}{20}$$

Add 22 and 3 to get 25.

$$\frac{25}{20}$$

Reduce the fraction \frac{25}{20} to lowest terms by extracting and canceling out 5.

$$\frac{5}{4}$$

Factor

$$\frac{5}{2 ^ {2}} = 1\frac{1}{4} = 1.25$$
