Question

$$\frac{ 11 }{ 18 } +- \frac{ 5 }{ 8 }$$

Evaluate

$-\frac{1}{72}\approx -0.013888889$

Solution Steps

Least common multiple of $18$ and $8$ is $72$. Convert $\frac{11}{18}$ and $\frac{5}{8}$ to fractions with denominator $72$.

$$\frac{44}{72}-\frac{45}{72}$$

Since $\frac{44}{72}$ and $\frac{45}{72}$ have the same denominator, subtract them by subtracting their numerators.

$$\frac{44-45}{72}$$

Subtract $45$ from $44$ to get $-1$.

$$-\frac{1}{72}$$

Factor

$-\frac{1}{72} = -0.013888888888888888$
