To find the simplest fraction of 90 out of 600, calculate like so:
- First of all, find the GCF (greatest common factor). In this case, it's 30.
- Then divide both 90 and 600 by 30
90÷600= 3/20
So, because you have already divided both numbers by the greatest possible shared number, this is the simplest fraction and can no longer be reduced.
Hope this helps!
