Question

On Saturday, 55% of the 200 people at Cordova Skating Rink brought their own skates. How many people did NOT bring their own skates?

Answer 1

If 55% of people brought their own skates, 45% did not.

Since 100 - 55 = 45.

45% of 200 = 90

The answer is: 90 people didn't bring their skates.
