Question

Sonia bought $\frac{2}{3}$ metre of ribbon and Monika $\frac{3}{5}$ metre of ribbon. What was the total length of the ribbon they bought?

Answer 1

Total length of the ribbon they bought

$$\begin{gathered} \frac{2}{3}+\frac{3}{5} \\ =\frac{5\times 2+3\times 3}{15} \\ =\frac{10+9}{15} \\ =\frac{19}{15} \end{gathered}$$

Thus, together they bought $\frac{19}{15}m$.
