Question

After typing 1/4 of a term paper on Friday, Richard completed 2/3 of the remainder on Saturday. If he wanted to finish the paper that weekend what part was left to be typed on Sunday?

Answer 1

Answer:
$\frac{7}{12}$ of the paper

Explanation:
On Friday:
Richard finished 0.25 of the term paper.
This means that:
Remaining = 1 - 0.25 = 0.75 of the paper

On Saturday:
Richard finished $\frac{2}{3}$ of the remainder.
This means that:
Richard finished $\frac{2}{3} * \frac{1}{4} = \frac{1}{6}$

Now, for Sunday:
We know that Richard finished 0.25 of the paper on Friday and $\frac{1}{6}$ of the paper on Saturday.
This means that:
Total finished = 0.25 + $\frac{1}{6}$ = $\frac{5}{12}$ of the paper
If he wants to finish it by Sunday, then:
He needs to type = 1 - $\frac{5}{12}$ = $\frac{7}{12}$ of the paper

Hope this helps :)
