Lapatulllka [165]

Answer:

$\frac{3}{5}$ th part of the bottle will be drunk by the calf.

Step-by-step explanation:

Part of the bottle fed by the piglet = $\frac{1}{5}$

Milk left in the bottle = 1 - $\frac{1}{5}$

= $\frac{5-1}{5}$

= $\frac{4}{5}$

Milk drunk by the calf = $\frac{3}{4}$ th of the left part

= $\frac{3}{4}\times \frac{4}{5}$

= $\frac{3}{5}$ th part of the bottle

Therefore, $\frac{3}{5}$ th part of the bottle will be drunk by the calf.
