Solve 2/5+3+1/2+2=

$$\frac { 2 } { 5 } + 3 + \frac { 1 } { 2 } + 2 =$$

Evaluate

$$\frac{59}{10}=5.9$$

Solution Steps

Convert 3 to fraction \frac{15}{5}.

$$\frac{2}{5}+\frac{15}{5}+\frac{1}{2}+2$$

Since \frac{2}{5} and \frac{15}{5} have the same denominator, add them by adding their numerators.

$$\frac{2+15}{5}+\frac{1}{2}+2$$

Add 2 and 15 to get 17.

$$\frac{17}{5}+\frac{1}{2}+2$$

Least common multiple of 5 and 2 is 10. Convert \frac{17}{5} and \frac{1}{2} to fractions with denominator 10.

$$\frac{34}{10}+\frac{5}{10}+2$$

Since \frac{34}{10} and \frac{5}{10} have the same denominator, add them by adding their numerators.

$$\frac{34+5}{10}+2$$

Add 34 and 5 to get 39.

$$\frac{39}{10}+2$$

Convert 2 to fraction \frac{20}{10}.

$$\frac{39}{10}+\frac{20}{10}$$

Since \frac{39}{10} and \frac{20}{10} have the same denominator, add them by adding their numerators.

$$\frac{39+20}{10}$$

Add 39 and 20 to get 59.

$$\frac{59}{10}$$

Factor

$$\frac{59}{2 \cdot 5} = 5\frac{9}{10} = 5.9$$
