each boy can eat one pizza/3 hours, so each one can eat 1 & 2/3 of a pizza in 5 hours.
5 pizzas will be eaten.

Lets break down the question and write it in math terms:
If 3 boys can eat 3 pizzas in 3 hours:
pizza's/hours
3/3
3 boys eat in 5 hours?
pizza's/hours
x/5 (note pizza's is x in this case because it is an unknown)
how many pizzas 3 boys eat in 5 hours?
3/3 (x/5)
cross multiply:
3(x)=3(5)
3x=15
solve for x:
x=15/3
x=5
So 3 boys can eat 5 pizza's in 5 hours.
Hope that was helpful! :)

3/(3*3) = x/(3*5)
x = 5 pizzas
-------
Ideas: The pizzas eating rate per boy is a constant.

Probably only 3 - they're all full after a pizza each so they can't eat any more pizza. Now ice cream, that's another matter altogether!

(3pizzas/3boys)/3hours = 1/3 pizza/boy/hour
1/3 * 3 * 5 = 5 pizzas

I HAVE TWO ANSWERS
1) THEY WILL STOP BECAUSE THEY ARE FULL
OR
2) THEY WILL EAT 15 PIZZAS
THATS IF YOU MEAN SLICES NPT THE WHOLE THING EACH ONE
