hi ur exam is prolly over but heres my ans, hope it helps 1. 3/4 can be written as 9:12 2. let the ratio of computers to pupils be 2u:15u where u is units (same as qn but i jus added the "units" for easier visualization) u will realize that 2 units will represent 50 computers. by simple proportion, find the value of 15 units : (50/2) x 15 = 225 pupils 3. let me rewrite the ratio in the form of 1:2:3:6 (total) - i simply added a last column to represent the total number of cookies by adding up the number of units in each bag (1 + 2 + 3 = 6). now u can realize that the total number of cookies is 30 and this is represented by 6 units (as we calculated from above) -> by simple proportion again, 6 units = 30 3 units = 15 (final ans) pls do more practices as ratio gets easier with more practices.

3/4 = 3:4 = 9/12 = 9:12 b is the 1st answer


2/15 =c/s= computers/students with 50 computers means 2/15 =50/s =1/15 = 25/s

so, s = 15x25 = 375 students, c is correct answer


30 cookies in 3 bags ratio 1:2:3

x +2x +3x = 6x = 30, x =5, 3x = 15 = # of cookies in bag with most cookies

bags have 5, 10 and 15 which sum to 30
