Answer this question:Noel bakes 4 dozen donuts for his class. There are 30 students in class, but only 80% like donuts. How many donuts does each student who likes donuts get to eat?
He makes 48 donuts because 4 x 12 = 48. 24 students want to eat donuts because 30 x .8 = 24. They can each eat 2 donuts because 48 / 24 = 2.
The answer is 2.

Answer this question:Haleigh decides that instead of throwing away old candles, she can use the last bit of wax combined together to make new candles. Each candle has 10% of it's original wax left. How many 5 ounce candles can she make if she has five 20 oz candles, 5 five ounce candles, and twenty-five one ounce candles?
She gets 2 ounces of wax from a 20 ounce candle because 20 x .1 = 2. She gets 10 ounces total from these candles because 5 x 2 = 10. She gets .5 ounces of wax from each five ounce candle because 5 x .1 = .5. She gets 1.5 ounces total from these candles because 5 x .5 = 2.5. She gets .1 ounces from each one ounce candle because 1 x .1 = .1. She gets 2.5 ounces from these candles because 25 x .1 = 2.5. She gets 15 ounces total because 10 + 2.5 + 2.5 = 15. She can make 3 candles because 15 / 5 = 3.
The answer is 3.

Answer this question:The ratio of boys to girls in a classroom is 3:5. If there are 4 more girls than boys, how many students are in the classroom?
Since the ratio of boys to girls is 3:5, then the class is divided into 3 + 5 = 8 parts. The girls have 5 - 3 = 2 parts more than the boys. Since 2 parts are equal to 4, then 1 part is equal to 4 / 2 = 2 students. Hence, there are 8 parts x 2 = 16 students.
The answer is 16.
