Question

Sarita bought <!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> $\frac{2}{5}$metre of ribbon and Lalita <!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> $\frac{3}{4}$metre of ribbon. What is the total length of the ribbon they bought?

Answer 1

Length of ribbon bought by Sarita = $\frac{2}{5}$ metres.

Length of ribbon bought by Lalita = $\frac{3}{4}$ metres.

Thus, total length of ribbon bought by them = $\frac{2}{5}$ + $\frac{3}{4}$

= $\frac{2\times 4}{5\times 4}$ + $\frac{3\times 5}{4\times 5}$

= $\frac{8}{20}$ + $\frac{15}{20}$

= $\frac{23}{20}$ = 1 $\frac{3}{20}$

So, they have bought 1 $\frac{3}{20}$ meters of ribbon in total.
