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 $=\frac{2}{5}$ metre.

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

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.
