Question

$$8\frac{3}{4}-1\frac{11}{20}$$

Evaluate

$\frac{36}{5}=7.2$

Solution Steps

Multiply $8$ and $4$ to get $32$.

$$\frac{32+3}{4}-\frac{1\times 20+11}{20}$$

Add $32$ and $3$ to get $35$.

$$\frac{35}{4}-\frac{1\times 20+11}{20}$$

Multiply $1$ and $20$ to get $20$.

$$\frac{35}{4}-\frac{20+11}{20}$$

Add $20$ and $11$ to get $31$.

$$\frac{35}{4}-\frac{31}{20}$$

Least common multiple of $4$ and $20$ is $20$. Convert $\frac{35}{4}$ and $\frac{31}{20}$ to fractions with denominator $20$.

$$\frac{175}{20}-\frac{31}{20}$$

Since $\frac{175}{20}$ and $\frac{31}{20}$ have the same denominator, subtract them by subtracting their numerators.

$$\frac{175-31}{20}$$

Subtract $31$ from $175$ to get $144$.

$$\frac{144}{20}$$

Reduce the fraction $\frac{144}{20}$ to lowest terms by extracting and canceling out $4$.

$$\frac{36}{5}$$
