Question: Cara has 60 marbles in a bag. 20 of them are yellow, half as many are green, and the remaining marbles are equally divided between red and blue. If Cara picks a marble at random, what are the odds it's blue (expressed as a percentage)?
Answer: First find the number of green marbles: 20 yellow marbles / 2 = 10 green marbles. Then find how many marbles are either red or blue: 60 marbles - 20 yellow marbles - 10 green marbles = 30 marbles. Divide this number in half to find how many marbles are blue: 30 marbles / 2 = 15 blue marbles. Finally, divide the number of blue marbles by the total number of marbles and multiply by 100 to find the percentage chance of getting a blue marble: 15 marbles / 60 marbles * 100 = 25%. The answer is 25.

Question: The school decided to add 20% to the gym budget. In a normal month, they could buy 15 dodgeballs for $5 each if they spent the entire budget on that. If they only buy softballs instead, which cost $9 each, how many can they buy with the new budget?
Answer: The old budget was $75 because 15 x 5 = 75. They are adding $15 to the budget because 75 x .2 = 15. The new budget is $90 because 75 + 15 = 90. They can buy 10 softballs on the new budget because 90 / 9 = 10. The answer is 10.

Total meatballs on the plates 3 x 3 = 9. If two - thirds are eaten, one - third remaining on the plates is 9 / 3 = 3. The answer is 3.
