Q:

Of the following, which is greater than ½ ?

Indicate ALL such fractions.

A) 2/5	B) 4/7
C) 4/9	D) 5/11

Answer & Explanation Answer: B) 4/7

Explanation:

One way to deal with fractions is to convert them all to decimals.

In this case all you would need to do is to see which is greater than 0.5.

Otherwise to see which is greater than ½, double the numerator and see if the result is greater than the denominator. In B doubling the numerator gives us 8, which is bigger than 7.
