Solve 9/2-20/1+1.5/1

$$\frac{ 9 }{ 2 } - \frac{ 20 }{ 1 } + \frac{ 1.5 }{ 1 }$$

Evaluate

$$-14$$

Solution Steps

Anything divided by one gives itself.

$$\frac{9}{2}-20+\frac{1.5}{1}$$

Convert 20 to fraction \frac{40}{2}.

$$\frac{9}{2}-\frac{40}{2}+\frac{1.5}{1}$$

Since \frac{9}{2} and \frac{40}{2} have the same denominator, subtract them by subtracting their numerators.

$$\frac{9-40}{2}+\frac{1.5}{1}$$

Subtract 40 from 9 to get -31.

$$-\frac{31}{2}+\frac{1.5}{1}$$

Anything divided by one gives itself.

$$-\frac{31}{2}+1.5$$

Convert decimal number 1.5 to fraction \frac{15}{10}. Reduce the fraction \frac{15}{10} to lowest terms by extracting and canceling out 5.

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

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

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

Add -31 and 3 to get -28.

$$\frac{-28}{2}$$

Divide -28 by 2 to get -14.

$$-14$$
