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.

so if each group have 4 adults just multiply 9 by 4,
therefore there will be 36.adults.
