Question

A medication states that the odds of having an allergic reaction are 1 in 50. What is that probability states as a percent?


1/5


1/10


1/20


1/500

Answer 1

Answer:

As a percent, the odds of having an allergic reaction would be 2%.

This is because 1 in 50 of a chance, is equal to 1/50, and to make this a percent out of 100, just multiply both parts of the fraction by 2.

None of the choices equal 1/50, so let's just make it a percentage anyway.

1/50 ---> 0.02

0.02 ---> 2%

The answer is 2%, or 1/50 as a fraction.
