Question

6. Solve: Ted typed 70% of his research paper before taking a break.
a. If he typed 7 pages, how many total pages are in the paper? ______________
b. How many pages does he have left to type? ____________________________

Answer 1

a. If Ted typed 70% of his research paper and typed 7 pages, we can use the equation:

70% of the total pages = 7

Dividing both sides of the equation by 70%, we get:

Total pages = 7 / 0.70 = 10

Therefore, the total number of pages in the paper is 10.

b. If Ted typed 70% of his research paper and there are 10 pages in total, we can calculate the number of pages he has left to type by finding the remaining percentage of the total pages:

100% - 70% = 30%

30% of the total pages = (30/100) * 10 = 3

Therefore, Ted has 3 pages left to type.
