Solve 3+1/10+7/100=

$$3 + \frac { 1 } { 10 } + \frac { 7 } { 100 } =$$

Evaluate

$$\frac{317}{100}=3.17$$

Solution Steps

Convert 3 to fraction \frac{30}{10}.

$$\frac{30}{10}+\frac{1}{10}+\frac{7}{100}$$

Since \frac{30}{10} and \frac{1}{10} have the same denominator, add them by adding their numerators.

$$\frac{30+1}{10}+\frac{7}{100}$$

Add 30 and 1 to get 31.

$$\frac{31}{10}+\frac{7}{100}$$

Least common multiple of 10 and 100 is 100. Convert \frac{31}{10} and \frac{7}{100} to fractions with denominator 100.

$$\frac{310}{100}+\frac{7}{100}$$

Since \frac{310}{100} and \frac{7}{100} have the same denominator, add them by adding their numerators.

$$\frac{310+7}{100}$$

Add 310 and 7 to get 317.

$$\frac{317}{100}$$

Factor

$$\frac{317}{2 ^ {2} \cdot 5 ^ {2}} = 3\frac{17}{100} = 3.17$$
