Question

The ratio of staff to students on a field trip is 3:16. If there are 18 staff, how many students are there?
Number

Answer 1

Answer:

96 students

Step-by-step explanation:

Let the amount of students be s.

3:16=18:s

Because we know that the product of the extremes equal to the product of the means, 3*s=16*18, which means 3s=288.

From here, we can conclude that s, the number of students, equal to 96.
