Question

What do we get when we subtract $\frac{5}{7}$ from 1$\frac{3}{7}$ ?

Answer 1

Converting the mixed fraction into improper fraction,
1$\frac{3}{7}$ = $\frac{(1\times 7)+3}{7}=\frac{10}{7}$

The fractions $\frac{5}{7}$ and $\frac{10}{7}$ are like fractions, as they have the same denominator.

To subtract like fractions, we have to subtract only the numerators and keep the denominator same.

So, $\frac{10}{7}-\frac{5}{7}=\frac{10-5}{7}=\frac{5}{7}$
