Question

At a train station, the ratio of the number of children to the number of adults is 4:7 There are 132 people altogether. How many more adults than children are there?

Answer 1

There are 48 children to 84 adults, you add up the 4:7 to get 11 parts, divide that by the total number which is 132, that gives you twelve parts. You then multiply 4x12 equals 48, then multiply 7 x12 to give 84. Giving you the ratio of children to adults 48:84.
