Question

Tyrone is converting 45/50 to a percent. Which method should he use to find the

percent?

A Divide the numerator and denominator of the fraction by 2.

B Subtract 40 from the numerator and denominator of the fraction.

C Multiply the numerator and the denominator of the fraction by 2.

D Add 50 to the numerator and denominator of the fraction.

Answer 1

C is the best method

Explanation:

Usually what I would do whenever I have this type of problem is match the denominator (bottom value) with 100.

I try and do this because all percentages are out of 100. For example you would say I got 90 percent. And this is equivalent to 90 over 100.

So, to make the denominator which is 50 into 100 I would need to multiply by 2.

Since whatever you do to the bottom you have to do to the top to keep the fraction equivalent, you would have to multiply the top by 2 as well.

45 * 2 = 90

50 * 2 = 100

So your answer would be C because he changes the bottom into an easy fraction to calculate percentage.

Sorry If my explanation is a little unclear. Hope you have your question solved. Ask me if you have any further questions.
