Sausages come in packets of 9. Bread rolls come in packets of 6. Colin wants to buy enough packs of sausages and rolls so that there are an equal number of sausages and rolls. What is the minimum number of sausages and rolls he needs to buy?

We  just  need  to  find  the  LCD  of  6  and 9 .....   this  =  18

 

So.....if he buys     18/ 9    =  2 package of sausages    and    18 / 6  =   3 packets of  rolls  he will have the same number

 

Proof   

2 * 9    =18

And

3 * 6   =18

first find the common multiple of 9 and 6.

then multiply both numbers by that number.

9x2=18

6x3=18

18x2=36
