Question

$$\frac { 9 } { 12 } + \frac { 1 } { 2 }$$

$\frac{5}{4}=1.25$

Reduce the fraction $\frac{9}{12}$ to lowest terms by extracting and canceling out $3$.

$$\frac{3}{4}+\frac{1}{2}$$

Least common multiple of $4$ and $2$ is $4$. Convert $\frac{3}{4}$ and $\frac{1}{2}$ to fractions with denominator $4$.

$$\frac{3}{4}+\frac{2}{4}$$

Since $\frac{3}{4}$ and $\frac{2}{4}$ have the same denominator, add them by adding their numerators.

$$\frac{3+2}{4}$$

Add $3$ and $2$ to get $5$.

$$\frac{5}{4}$$

$\frac{5}{2 ^ {2}} = 1\frac{1}{4} = 1.25$
