Question

Colin needs to write a 6-page essay. If he writes 3/4 of a page each night, how many nights will it take him to finish the essay? 5 nights 7 nights 6 nights 8 nights

Answer 1

8 nights

Explanation:

3/4 pages a night. So if there are six pages, 3/4 + 3/4 = 6/4. 6/4 + 3/4 = 9/4 in 3 nights. 9/4 + 3/4 = 12/4 or 3 pages in 4 nights, If we double this,

3 x 2 = 6 pages and 4 x 2 = 8 nights.

Answer 2

Answer: 8 nights

Explanation:

Let the total number of nights be X

(3/5)X = 6

X = 6/(3/4)

X = 6 * 4/3 (invert the fraction )

X = 24/3

X = 8 nights
