Question

$$\frac { 4 } { 9 } - \frac { 1 } { 4 } =$$

$\frac{7}{36}\approx 0.194444444$

Least common multiple of $9$ and $4$ is $36$. Convert $\frac{4}{9}$ and $\frac{1}{4}$ to fractions with denominator $36$.

$$\frac{16}{36}-\frac{9}{36}$$

Since $\frac{16}{36}$ and $\frac{9}{36}$ have the same denominator, subtract them by subtracting their numerators.

$$\frac{16-9}{36}$$

Subtract $9$ from $16$ to get $7$.

$$\frac{7}{36}$$

$\frac{7}{2 ^ {2} \cdot 3 ^ {2}} = 0.19444444444444445$
