$$\text{A tailor has }15\frac{3}{4}\,\text{ meters of fine silk; if making one kurta requires }2\frac{1}{4}\,\text{ meters of silk, exactly how many kurtas can he make? \lbrack Page No. 53\rbrack}$$

$$\text{Total silk} = 15\frac{3}{4} = \frac{63}{4} \text{ m.}$$

$$\text{Per kurta} = 2\frac{1}{4} = \frac{9}{4} \text{ m.}$$

$$\begin{aligned}\text{Number of kurtas} & =\frac{63}{4}\div\frac{9}{4}=\frac{63}{4}\times\frac{4}{9}\\ & =\frac{63}{9}=7\end{aligned}$$

He can make exactly 7 kurtas.
