Example Question #1 : Fractions

Which of the following is greater than 1/2 ?

Possible Answers:

2/5

4/9

9/19

6/11

8/17

Correct answer:

6/11

Explanation:

There are two ways to deal with fractions. One way is to convert them all to decimals. (By using your calculator, divide the numerator by the denominator). Using this method all you would need to do is to see which is greater than 0.5.  Otherwise to see which is greater than 1/2, double the numerator and see if the result is greater than the denominator. In B, the correct answer, doubling the numerator gives us 12, which is bigger than 11.
