Answer 1

Given:

The infant prepared 2/5 of the presentation  on Tuesday night, 1/3 of the remaining presentation on Wednesday night

To Find:

What fraction  of the original presentation would Infant have to do on Thursday night to perform the  presentation on Friday morning?​

Solution:

Let's assume the total original presentation content be = x

$\begin{center}\begin{tabular}{ c c c }\\ & Content Prepared & Remaining Content \\\\\\ Tuesday night & \frac{2}{5} x & x - \frac{2}{5} x = \frac{3}{5} x \\\\ Wednesday night & \frac{1}{3} \times \frac{3}{5} x = \frac{1}{5} x & \frac{3}{5} x - \frac{1}{5} x = \frac{2}{5} x \\\\Thursday night & \frac{2}{5} x\end{tabular}\end{center}$

Hence, 2/5 of the original presentation prepared on Thursday night.
