Question

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

Answer 1

To solve this problem we can use equation.
If we assume that x is number of crocodiles, we can say that number of alligators is 4*x because its 4 times more.
We know that together is 40, so we have
x+4*x=40
Now we are reducing.
5x=40     /:5    dividing both sides by 5
x=9 - number of alligators
