work out the number of freezers and cookers sold that week.

Answer 1

Hi Kern,

 

The easiest way to view ratio that works for me is this:

 

Instead of seeing 5:2

 

I see      2            freezers

           -----   =  -------------

             5            cookers

 

in other words, there are 5 cookers for every 2 freezers

 

When you write it this way you can know to write your equation as such

 

             2            freezers               140 - cooker
           -----   =  ------------- =     ------------------

             5            cookers                  cooker

 

=> cooker = 100

 

Freezer = 140 -100 = 40

 

40/100 = 4/10 = 2/5
