Question

A bag of sweets contains only gobstoppers and sherbert lemons.

There are 3 gobstoppers for every 4 sherbert lemons.
There are 56 sweets in the bag. How many gobstoppers are there?

Answer 1

Total: 56 sweets
gob + lem -> 3+4 = 7 (sweets in a "group")
56/7 = 8 (we have 8 "groups")
gobstoppers = their num in 1 "group" • num of "groups", so 3 • 8 = 24

Answer: 24 gobstoppers
