Question

Santa bought $\frac{2}{5}$ metre of ribbon and Lalita $\frac{3}{4}$ metre of ribbon. What is the total length of the ribbon they bought?

Answer 1

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

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

Total length of ribbon bought by them

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

$=\frac{(2\times 4)+(3\times 5)}{20}$

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

$=\frac{23}{20}m$
