Question

$$\frac{2}{10}+\frac{3}{8}-\frac{1}{4}$$

Evaluate

$\frac{13}{40}=0.325$

Solution Steps

Reduce the fraction $\frac{2}{10}$ to lowest terms by extracting and canceling out $2$.

$$\frac{1}{5}+\frac{3}{8}-\frac{1}{4}$$

Least common multiple of $5$ and $8$ is $40$. Convert $\frac{1}{5}$ and $\frac{3}{8}$ to fractions with denominator $40$.

$$\frac{8}{40}+\frac{15}{40}-\frac{1}{4}$$

Since $\frac{8}{40}$ and $\frac{15}{40}$ have the same denominator, add them by adding their numerators.

$$\frac{8+15}{40}-\frac{1}{4}$$

Add $8$ and $15$ to get $23$.

$$\frac{23}{40}-\frac{1}{4}$$

Least common multiple of $40$ and $4$ is $40$. Convert $\frac{23}{40}$ and $\frac{1}{4}$ to fractions with denominator $40$.

$$\frac{23}{40}-\frac{10}{40}$$

Since $\frac{23}{40}$ and $\frac{10}{40}$ have the same denominator, subtract them by subtracting their numerators.

$$\frac{23-10}{40}$$

Subtract $10$ from $23$ to get $13$.

$$\frac{13}{40}$$
