Solution Steps

Reduce the fraction \frac{20}{100} to lowest terms by extracting and canceling out 20.

$$\left(\frac{1}{5}+1.8\right)\times 2.5$$

Convert decimal number 1.8 to fraction \frac{18}{10}. Reduce the fraction \frac{18}{10} to lowest terms by extracting and canceling out 2.

$$\left(\frac{1}{5}+\frac{9}{5}\right)\times 2.5$$

Since \frac{1}{5} and \frac{9}{5} have the same denominator, add them by adding their numerators.

$$\frac{1+9}{5}\times 2.5$$

Add 1 and 9 to get 10.

$$\frac{10}{5}\times 2.5$$

Divide 10 by 5 to get 2.

$$2\times 2.5$$

Multiply 2 and 2.5 to get 5.

$$5$$
