Question
There are 500 students in a rural school. If 370 of them can swim, what percentage of them can swim and what percentage cannot?
Solution
Total number of students = 500
Number of students who can swim = 370
Percentage of students who can swim = `370/500 xx 100%` = 74%
Number of students who cannot swim = 500 – 370 = 130
Percentage of students who cannot swim = `130/500 xx 100%` = 26%
i.e. 74% can swim and 26% cannot swim

Sunscreens block harmful ultraviolet (UV) rays produced by the sun. Each sunscreen has a Sun Protection Factor (SPF) that tells you how many minutes you can stay in the sun before you receive one minute of burning UV rays. For example, if you apply sunscreen with SPF 15, you get 1 minute of UV rays for every 15 minutes you stay in the sun.
A label on a sunscreen with SPF 30 claims that the sunscreen blocks about 97% of harmful UV rays. Assuming the SPF factor is accurate, is this claim true? Explain.
