Question

$$\frac { 7 } { 10 } - \frac { 7 } { 12 }$$

$\frac{7}{60}\approx 0.116666667$

Least common multiple of $10$ and $12$ is $60$. Convert $\frac{7}{10}$ and $\frac{7}{12}$ to fractions with denominator $60$.

$$\frac{42}{60}-\frac{35}{60}$$

Since $\frac{42}{60}$ and $\frac{35}{60}$ have the same denominator, subtract them by subtracting their numerators.

$$\frac{42-35}{60}$$

Subtract $35$ from $42$ to get $7$.

$$\frac{7}{60}$$

$\frac{7}{2 ^ {2} \cdot 3 \cdot 5} = 0.11666666666666667$
