Question

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

Answer 1

$\text{Converting the mixed fraction into improper}\text{fraction,}1\frac{3}{7}=\frac{(1\times 7)+3}{7}=\frac{10}{7}$$\mathrm{The}\mathrm{fractions}\frac{5}{7}\mathrm{and}\frac{10}{7}\mathrm{are}\mathrm{like}\mathrm{fractions}\mathrm{as}\mathrm{they}\mathrm{have}\mathrm{the}\mathrm{same}\mathrm{denominator}.$

$\text{To subtract like fractions, subtract only the}\text{numerators and keep the denominators same.}$

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