There are 4 times as many alligators as crocodiles. If the total number of alligators and crocodiles is 40, how many alligators are there

You need to put them in groups of 5 (4 alligators+1 crocodile)

40/5=8 groups

32 alligators, 8 crocodile

X=crocodiles

so since there's 4 times as many alligators, then we multiply 4 and x to get 4x

Now, we have a total of 40 crocodiles and alligators, so we can make the equation:

4x=40 to find how many crocs there are. So if we divide 4x form both sides,

x=10.

so there are 10
