3:8 = 12:x so multiply 8 by 4 which is 32 so 3:8 = 12:32. The next one is 3:8 = x:48 So for this, you can multiply 3 by 6 to get 18:48 as your answer.
7+5 is 12. 114 divided by 12 is 9.5 so one part is 9.5. Dipaks share is 5 so 9.5 multiplied by 5 is 47.5 so the answer is $47.50
75/4=25 pages per hour, so, now we have to divide 250 by 25.
250/25=10
So, it would take Joan 10 hours to read 250 pages. :)
28/80 and then you simplify it by dividing the numerator and denominator by 4 and you get 7/20.
