Answer 2

$\huge\underline\mathrm{Question:-}$

• To find appropriate properties for the sum.

$\huge\underline\mathrm{Solution:-}$

$⟹ \frac{2}{7} \times \frac{7}{16} + \frac{21}{4}$

Cross Multiply here!

$⟹ \frac{2}{7} \times \frac{7 + 84}{16}$

$\frac{2}{7} \times \frac{91}{16}$

$\frac{\cancel{182}}{\cancel{112}}$

$\frac{\cancel{91}}{\cancel{56}}$

$⟹ \frac{13}{8}$
