Question 7589
convert the fractions so that they have the same denominator... in this example make them both 12... so 3/4 is the same as 9/12. Hopefully you are OK with this? both mathematically and common sense wise i mean.


so we now have 9/12 - 5/12


(9-5)/12
--> 4/12


which simplifies back down to 1/3
