Tommy has a lot of Lego blocks, but only green and red blocks. There are four times as many green blocks as there are red blocks. If Tommy has Y Lego blocks, how many red blocks are there, in terms of Y.
Answers.
A) 3*Y	B) Y/3	C) Y/5	D) Y/4	E) Y/6
Since Y equals the number of blocks, then Y = Green + Red   Since there are four times green blocks as red blocks, then Green = 4*Red   Thus Y = 4*Red + Red, which simplifies to Y=5*Red   Therefore the Red = Y/5   Answer: Y/5
