Answer 1

Merry gifted 20 apples to Nexus and Nellie

Part of total apples eaten by Nexus and Nellie together $=\frac{4}{5}$

Out of 20 apples, number of apples eaten only by Nexus $=4$

That means Nexus ate $\frac{4}{20}=\frac{1}{5}$ part of total number of apples.

$\therefore$ Part of total number of apples eaten only by Nellie = Part of number of apples eaten by Nexus and Nellie together - Part of number of apples eaten only by Nexus
$=\frac{4}{5}-\frac{1}{5}=\frac{3}{5}$

Part or Fraction of 20 apples that Nellie ate on its own $=\frac{3}{5}$

Numerator of the fraction is 3.
