Question

110 students go on a school trip. Each student needs a bottle of water. Each pack has 6 bottles. How many of these packs are needed?

Answer 1

110 students are going on a trip, and each student needs one water bottle.

So we multiple 110 students* 1 water bottle each to get 110 water bottles are needed for all the students.

There are 6 water bottles in a pack- and we need 110 water bottles.

So divide the number of water bottles needed by the amount in a pack.

110/6= 18 1/3

We need 18 packs a little bit more- so we round 18 up because we can't buy 1/3 of a pack or have students go thirsty.

So we need 19 packs of water for the students on the trip.
