Verified Answer :

let's just make 15 students a group. how many groups are there if there r 135 student? 135/15 = 9 groups.
so if each group have 4 adults just multiply 9 by 4,
therefore there will be 36.adults.

Answer:

There would be 36 adults on the field trip.

Step-by-step explanation:

Given,

There are 4 chaperone for every 15 students who attend a school field trip,

So, the ratio of the chaperone and students = \(\frac{4}{15}\)

Let there are x chaperone for 135 students,

So, the ratio of the chaperone and students = \(\frac{x}{135}\)

\(\implies \frac{x}{135}=\frac{4}{15}\)

\(15x = 4\times 135\)

\(x=\frac{4\times 135}{15}=4\times 9=36\)

Hence, there would be 36 adults on the field trip.
