$$\frac{4}{5}+\frac{3}{10}+\frac{3}{20}$$

Evaluate

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

Solution Steps

Least common multiple of $5$ and $10$ is $10$. Convert $\frac{4}{5}$ and $\frac{3}{10}$ to fractions with denominator $10$.

$$\frac{8}{10}+\frac{3}{10}+\frac{3}{20}$$

Since $\frac{8}{10}$ and $\frac{3}{10}$ have the same denominator, add them by adding their numerators.

$$\frac{8+3}{10}+\frac{3}{20}$$

Add $8$ and $3$ 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 $5$.

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