Question

$$\frac { 3 } { 18 } - \frac { 5 } { 27 }$$

$-\frac{1}{54}\approx -0.018518519$

Reduce the fraction $\frac{3}{18}$ to lowest terms by extracting and canceling out $3$.

$$\frac{1}{6}-\frac{5}{27}$$

Least common multiple of $6$ and $27$ is $54$. Convert $\frac{1}{6}$ and $\frac{5}{27}$ to fractions with denominator $54$.

$$\frac{9}{54}-\frac{10}{54}$$

Since $\frac{9}{54}$ and $\frac{10}{54}$ have the same denominator, subtract them by subtracting their numerators.

$$\frac{9-10}{54}$$

Subtract $10$ from $9$ to get $-1$.

$$-\frac{1}{54}$$

$-\frac{1}{54} = -0.018518518518518517$
