3 typists working together can type 36 pages in 30 minutes. The ratio of the three typists are 4:3:2. How long will it take the slowest working alone to type 52 pages?

Not sure what I'm doing wrong. I got 4:3:2 = 9

Divide 36 by 9 so you get 4 for each 1 in the ratio

(4:3:2) * 4 = 16:12:8

Not sure what to do after this. I know they want the slowest rate, which I think is 8. Do I need to convert this into an hour rate or something?

so the slowest one can type 8 pages in 30 mins , to finish 52 pages he needs (52/8)*30 = 195 mins

It's an easy one, i am really surprised every one got it wrong.

4:3:2 -> 4+3+2=9

in 30 min- 36 --> 72 in 1 hour.

the slowest one gets 2/9 *72 = 16 pages in one hour.

she will get 52 in 3.25 hours --> 52/16= 3.25
