Stephen read a 90-page book in 6 days. If he continues reading at that rate, how long will it take him to read a 300-page book?
thankss

Answer 1

90/6 = 300/n
90n = 1800
n = ....

Answer 2

I am sorry I dont get it how?

Answer 3

I set up a simple ratio

or
he can read 90 pages in 6 days,
so he can read 15 pages per day

so the number of days for 300 pages is
300/15 or 20 days

Answer 4

So i will write down that he 15 pages per day so its the same as 90 pages in six days so now the number of days is 20 days or 300/15 days?

By the way thanku

Answer 5

90pages/15days =6 pages/day.
6 * d = 300,
d = 50 days.

Answer 6

nice.
