Mark the correct alternative in each of the following:

$2\frac{3}{5}÷\frac{5}{7}=$

(a) $\frac{13}{7}$ (b) $\frac{13}{25}$ (c) $\frac{91}{25}$ (d) $\frac{25}{91}$

Answer 1

$$\begin{gathered} 2\frac{3}{5}÷\frac{5}{7} \\ =\frac{13}{5}÷\frac{5}{7} \\ =\frac{13}{5}\times \frac{7}{5} \\ =\frac{13\times 7}{5\times 5} \\ =\frac{91}{25} \end{gathered}$$

Hence, the correct answer is option (c).
