Tom ate 1/4 of a pizza. he divided the leftover pizza into pices each equal to 1/12 of the original pizza. after he gave some friends 1 piece each, 1/6th of the original pizza remained. how many friends got pizza?

So, there are 12 pieces. since he ate 1/4 of it already, he divided the rest to 1/12 each equivlent to a whole pizza. since 1/6 of it was left, so, he got 1/4 for himself, each friend had one, then 1/6 was left. before, he made it equivlent to a twelve piece minus 4. 12 - 4 = 8, 1/6 means 6 pieces or 3 for 12. final answer, it would most likely be 6 or 4. thank you.
