Question: Find the answer to this math problem: Johnny is picking up the toys on the floor of his room.  He'd dumped a lego boxed set with 500 pieces on the floor, and another one that had 3 times more pieces than the 500 piece one, and another one that had 1/4 the number of pieces.  How many blocks does Johnny pick up if he picks up all the legos?
Answer: 
The first set had 500 pieces, and the second set had 3 times as many as the first set, so the second set has 500*3=1500 pieces
The third set had one-quarter of the 500 pieces, so that means it had 500*.25= 125 pieces
In total, that means Johnny picked up 500 + 1500+ 125= 2125 blocks
