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:

$\frac{1}{10}$

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

$126\times\frac{1}{10}=\frac{126\times1}{10}=\frac{126}{10}=12.6$

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