Hi can someone Help me ?
The number of cartons of juices to the number of cartons of milk to the number of cartons of soft drinks is in the ratio of 12 : 5 : 1. There are 66 more cartons of juices than soft drinks. How many cartons of milk are there?
j : m : s = 12 : 5 : 1 or 12k : 5k : k
there are 66 more juices than soft drinks
12k = k + 66
k = 6
milk = m = 5k = 30
30 cartons of milk
check
if k=6, we have
72 juices, 30 milk and 6 soft drinks
66 more juices than soft drinks ? , yes
ratio:
72 : 30 : 6
= 12 : 5 : 1 , yes
