Find the GCF (Greatest Common Factor) of both numbers. It is 3.
Divide both numbers by the GCF.
The simplest form is 1/3.
So, you see that when 2 pieces is considered a group, that means you have to divide. So, you divide 50/2 and it gives you 25.
Hope this helps :)
For each tank just divide the number of L by the number of fish to get the volume or fish.
For tank A it is 40/5=8, for tank B it is 100/12=8.3, and for tank C it is 180/23=7.8.
If you number them least to greatest, it is (tank C, tank A, tank B)
