Question

$$\frac{ 18 }{ 32 } - \frac{ 17 }{ 20 } =$$

Evaluate

$-\frac{23}{80}=-0.2875$

Solution Steps

Reduce the fraction $\frac{18}{32}$ to lowest terms by extracting and canceling out $2$.

$$\frac{9}{16}-\frac{17}{20}$$

Least common multiple of $16$ and $20$ is $80$. Convert $\frac{9}{16}$ and $\frac{17}{20}$ to fractions with denominator $80$.

$$\frac{45}{80}-\frac{68}{80}$$

Since $\frac{45}{80}$ and $\frac{68}{80}$ have the same denominator, subtract them by subtracting their numerators.

$$\frac{45-68}{80}$$

Subtract $68$ from $45$ to get $-23$.

$$-\frac{23}{80}$$

Factor

$-\frac{23}{80} = -0.2875$
