Question

Can someone help me with number two please?

Answer 1

So if they wrote 25% of the 12 total pages in class that would leave 9 pages left to do.
25% of 12 = 9

Then if they wrote 50% of the remaining 9 pages that would give you 4.5
50% of 9 = 4.5

So then we would add up the two totals to get 7.5
4.5 + 3 = 7.5

Lastly, we would subtract 7.5 from 12 to get our remaining number of pages left to be written
12-7.5=4.5

Answer 2

So far Andrea and her partner have completed 75% of the 12-page essay, that means they still have to complete 25%.

What you have to do is find 25% of 12

The first thing you should do is turn 25% into a decimal and then multiply it by 12 and the final answer should equal the number of pages that Andrea and her partner have left to write.

So, 0.25*12=3 Therefore they have 3 pages left to write.
