Question

$$2\frac{4}{5}+\frac{1}{2}+\frac{3}{4}$$

Evaluate

$\frac{81}{20}=4.05$

Solution Steps

Multiply $2$ and $5$ to get $10$.

$$\frac{10+4}{5}+\frac{1}{2}+\frac{3}{4}$$

Add $10$ and $4$ to get $14$.

$$\frac{14}{5}+\frac{1}{2}+\frac{3}{4}$$

Least common multiple of $5$ and $2$ is $10$. Convert $\frac{14}{5}$ and $\frac{1}{2}$ to fractions with denominator $10$.

$$\frac{28}{10}+\frac{5}{10}+\frac{3}{4}$$

Since $\frac{28}{10}$ and $\frac{5}{10}$ have the same denominator, add them by adding their numerators.

$$\frac{28+5}{10}+\frac{3}{4}$$

Add $28$ and $5$ to get $33$.

$$\frac{33}{10}+\frac{3}{4}$$

Least common multiple of $10$ and $4$ is $20$. Convert $\frac{33}{10}$ and $\frac{3}{4}$ to fractions with denominator $20$.

$$\frac{66}{20}+\frac{15}{20}$$

Since $\frac{66}{20}$ and $\frac{15}{20}$ have the same denominator, add them by adding their numerators.

$$\frac{66+15}{20}$$

Add $66$ and $15$ to get $81$.

$$\frac{81}{20}$$
