Solve 0.3^2+2/5

$$0.3 ^ { 2 } + \frac { 2 } { 5 }$$

Evaluate

$$0.49$$

Solution Steps

Calculate 0.3 to the power of 2 and get 0.09.

$$0.09+\frac{2}{5}$$

Convert decimal number 0.09 to fraction \frac{9}{100}.

$$\frac{9}{100}+\frac{2}{5}$$

Least common multiple of 100 and 5 is 100. Convert \frac{9}{100} and \frac{2}{5} to fractions with denominator 100.

$$\frac{9}{100}+\frac{40}{100}$$

Since \frac{9}{100} and \frac{40}{100} have the same denominator, add them by adding their numerators.

$$\frac{9+40}{100}$$

Add 9 and 40 to get 49.

$$\frac{49}{100}$$

Factor

$$\frac{7 ^ {2}}{2 ^ {2} \cdot 5 ^ {2}} = 0.49$$
