7)3000/5000*100=60%
8)7000-6000=1000
1000/7000*100=14.3%
9)33.6/2.1=16
10)201.15/1.25 =160.92 but you only round up in order to get it fill so 161 jugs
Answer:
12 : 15 : 10
Step-by-step explanation:
Let A = 4x, the B = 5x
Let B = 3y, then C = 2y
B = 5x = 3y, so y = (5/3)x
Let x = 3t, so y = 5t
Then A = 4x = 4(3t) = 12t
B = 5x = 5(3t) = 15t
C = 2y = 2(5t) = 10t
so A : B : C = 12t : 15t : 10t = 12 : 15 : 10
