Solution Steps

Reduce the fraction \frac{8}{10} to lowest terms by extracting and canceling out 2.

$$1-\frac{4}{5}=\frac{2}{10}\text{ and }\frac{2}{10}=\frac{1}{5}$$

Convert 1 to fraction \frac{5}{5}.

$$\frac{5}{5}-\frac{4}{5}=\frac{2}{10}\text{ and }\frac{2}{10}=\frac{1}{5}$$

Since \frac{5}{5} and \frac{4}{5} have the same denominator, subtract them by subtracting their numerators.

$$\frac{5-4}{5}=\frac{2}{10}\text{ and }\frac{2}{10}=\frac{1}{5}$$

Subtract 4 from 5 to get 1.

$$\frac{1}{5}=\frac{2}{10}\text{ and }\frac{2}{10}=\frac{1}{5}$$

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

$$\frac{1}{5}=\frac{1}{5}\text{ and }\frac{2}{10}=\frac{1}{5}$$

Compare \frac{1}{5} and \frac{1}{5}.

$$\text{true}\text{ and }\frac{2}{10}=\frac{1}{5}$$

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

$$\text{true}\text{ and }\frac{1}{5}=\frac{1}{5}$$

Compare \frac{1}{5} and \frac{1}{5}.

$$\text{true}\text{ and }\text{true}$$

The conjunction of \text{true} and \text{true} is \text{true}.

$$\text{true}$$
