Place the following fractions into order from highest to lowest

7/4 1/6 7/2 - Jul 6th 2008, 04:17 AMMatt Westwood
Easiest way to compare 2 fractions is to give them a common denominator.

The quickest way to do that is to multiply top and bottom of the one fraction with the bottom of the other, and vice versa.

So for 7/4 and 1/6, you multiply top and bottom of 7/4 by 6, and top and bottom of 1/6 by 4.

This gives you 42 / 24 compared with 4/24 and the ordering of these is obvious.

It occurs to me there's a quick way of doing it by eye in this case:

7/4 is between 1 and 2, 7/2 is between 3 and 4 and 1/6 is between 0 and 1. - Jul 6th 2008, 04:18 AMjeri2008

Lets change it to decimal numbers.

To 3 decimal places.

Can you place this in order from highest to lowest? - Jul 6th 2008, 04:37 AMjeri2008...
