Question

Attendance at the homecoming game decreased from 5760 fans last year to 4320 fans this year. How do you find the percent of decrease?

Answer 1

The number of fans decreased by `25%` since last year.

Explanation:

The number of fans decreased from `5760` to `4320` over one year.
That makes a difference of `5760-4320=1440` between this year and last year.
Compare this difference with the original number of fans and you will obtain the following ratio: `1440/5760=1/4`
Multiply this ratio by 100 and you obtain the percentage of decrease: `1/4*100=25`
