Question

Subtract :

$\frac{21}{43}-\frac{19}{43}$

Answer 1

We know that when we have to add or subtract like fractions, we just need to add or subtract the numerators while the denominator remains the same.

$$\begin{gathered} \frac{21}{43}-\frac{19}{43}=\frac{21-19}{43} \\ =\frac{2}{43} \end{gathered}$$

Hence the difference is$\frac{2}{43}$.
