Solve 100+25+2/5+3/10+40

$$100 + 25 + \frac { 2 } { 5 } + \frac { 3 } { 10 } + 40$$

Evaluate

$$\frac{1657}{10}=165.7$$

Solution Steps

Add 100 and 25 to get 125.

$$125+\frac{2}{5}+\frac{3}{10}+40$$

Convert 125 to fraction \frac{625}{5}.

$$\frac{625}{5}+\frac{2}{5}+\frac{3}{10}+40$$

Since \frac{625}{5} and \frac{2}{5} have the same denominator, add them by adding their numerators.

$$\frac{625+2}{5}+\frac{3}{10}+40$$

Add 625 and 2 to get 627.

$$\frac{627}{5}+\frac{3}{10}+40$$

Least common multiple of 5 and 10 is 10. Convert \frac{627}{5} and \frac{3}{10} to fractions with denominator 10.

$$\frac{1254}{10}+\frac{3}{10}+40$$

Since \frac{1254}{10} and \frac{3}{10} have the same denominator, add them by adding their numerators.

$$\frac{1254+3}{10}+40$$

Add 1254 and 3 to get 1257.

$$\frac{1257}{10}+40$$

Convert 40 to fraction \frac{400}{10}.

$$\frac{1257}{10}+\frac{400}{10}$$

Since \frac{1257}{10} and \frac{400}{10} have the same denominator, add them by adding their numerators.

$$\frac{1257+400}{10}$$

Add 1257 and 400 to get 1657.

$$\frac{1657}{10}$$

Factor

$$\frac{1657}{2 \cdot 5} = 165\frac{7}{10} = 165.7$$
