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

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.
