Solve 15/3-7/2+31/2=

$$\frac { 15 } { 3 } - \frac { 7 } { 2 } + \frac { 31 } { 2 } =$$

Evaluate

$$17$$

Solution Steps

Divide 15 by 3 to get 5.

$$5-\frac{7}{2}+\frac{31}{2}$$

Convert 5 to fraction \frac{10}{2}.

$$\frac{10}{2}-\frac{7}{2}+\frac{31}{2}$$

Since \frac{10}{2} and \frac{7}{2} have the same denominator, subtract them by subtracting their numerators.

$$\frac{10-7}{2}+\frac{31}{2}$$

Subtract 7 from 10 to get 3.

$$\frac{3}{2}+\frac{31}{2}$$

Since \frac{3}{2} and \frac{31}{2} have the same denominator, add them by adding their numerators.

$$\frac{3+31}{2}$$

Add 3 and 31 to get 34.

$$\frac{34}{2}$$

Divide 34 by 2 to get 17.

$$17$$

Factor

$$17$$
