Cross Multplying

Hi Guys!

Yesterday we learnt the Cross Multiplying strategy. The Cross Multiplying strategy is used to see which is bigger between two fractions. You can only use this strategy with two fractions, not three or more because it won´t work. an example is  3/4 and 1/2. 3/4 is bigger than 1/2, the way you work this out is you times 3×2 and 1×4. Everyone knows that 3×2 is bigger than 1×4 and that means 3/4 is bigger than 1/2. Have you ever used the Cross Multiplying strategymy god!?
