There were 250 roses and 450 pansies in a garden. If a gardener packed them into bags and each bag contained 5 flowers, how many more bags of pansies are there than bags of roses?
You must find the number of bags of roses and the number of bags of pansies and subtract the two.
Bags of roses: 250 ÷ 5 = 50 bags
Bags of pansies: 450 ÷ 5 = 90 bags
The difference: 90 50 = 40 more bags of pansies
