Question

Subtract and express the differences in simplest form:

$\frac{19}{22}-\frac{17}{22}=\_\_\_$

Answer 1

• Step 1: As these are the like fractions, subtract the numerators and write the difference over the common denominator.

$\frac{19}{22}-\frac{17}{22}=\frac{19-17}{22}=\frac{2}{22}$

• Step 2: It can be observed that $2$ is the common factor of $2$ and $22$. Divide the numerator and denominator by the common factor $2$.

$\frac{2÷2}{22÷2}=\frac{1}{11}$

• Hence, the simplest form of $\frac{2}{22}$ is $\frac{1}{11}$.
