Solution Steps

Least common multiple of 5 and 20 is 20. Convert \frac{4}{5} and \frac{3}{20} to fractions with denominator 20.

$$\frac{16}{20}-\frac{3}{20}=\frac{1}{20}-\frac{1}{20}$$

Since \frac{16}{20} and \frac{3}{20} have the same denominator, subtract them by subtracting their numerators.

$$\frac{16-3}{20}=\frac{1}{20}-\frac{1}{20}$$

Subtract 3 from 16 to get 13.

$$\frac{13}{20}=\frac{1}{20}-\frac{1}{20}$$

Subtract \frac{1}{20} from \frac{1}{20} to get 0.

$$\frac{13}{20}=0$$

Compare \frac{13}{20} and 0.

$$\text{false}$$
