Question

QUESTION 4One hundred twenty sixth graders are going on a field trip toSea World. The ratio of chaperones to students must be 1:10.How many chaperones are needed for the trip?A) 12B) 13C) 14D) 15

Answer 1

We can express the ratio of chaperones to students 1 : 10 as a fraction, like this:

`(1)/(10)`

By multiplying the number of students by the above ratio, we get the number of needed chaperones, like this:

`126*(1)/(10)=(126*1)/(10)=(126)/(10)=12.6`

Rounding to the nearest integer, the number of chaperones needed for the trip is 13
