Answer 1

Using proportions, we have that:

• 125% of last year's attendance is of 270.

• 25% of last year's attendance is of 54.

• 100% of last year's attendance is of 216.

What is a proportion?

A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures.

We have that last year's amount is of x, and 125% of that is 270, hence:

1.25x = 270

x = 270/1.25

x = 216.

100% of last year's attendance is of 216.

25% of last year's attendance is given by:

0.25 x 216 = 54.
