There are 60 marbles in a bowl. Their colors are red, blue, and yellow. 1/3 of the marbles are yellow, and 1/4 of the marbles are blue. How many red marbles are there in the bowl?
Correct Answer
B. 25
Explanation
Since 1/3 of the marbles are yellow and 1/4 of the marbles are blue, the remaining fraction of marbles must be red. To find the number of red marbles, we need to subtract the number of yellow and blue marbles from the total number of marbles. 1/3 of 60 is 20, and 1/4 of 60 is 15. Therefore, there are 60 - 20 - 15 = 25 red marbles in the bowl.

D. 208
Explanation
26 multiplied by 8 equals 208. Multiplication is the process of repeated addition, where you add one number (the multiplicand) to itself a certain number of times (the multiplier). In this case, you add 26 to itself 8 times, resulting in a total of 208.

How many legs (total) do 4 dogs, 2 elephants, 15 cats, and 26 people have?
Correct Answer
C. 136
Explanation
The total number of legs can be calculated by multiplying the number of each animal by the number of legs each animal has, and then summing them all up. 4 dogs have 4 legs each, 2 elephants have 4 legs each, 15 cats have 4 legs each, and 26 people have 2 legs each. Therefore, the total number of legs is 4*4 + 2*4 + 15*4 + 26*2 = 16 + 8 + 60 + 52 = 136.

John works 4 days per week. He drives 10 miles round trip per day. If gas is $2.50 per gallon and his car gets 20 miles to the gallon, how much would he have spent on gasoline in 2 weeks getting back and forth to work?
Correct Answer
B. $10.00
Explanation
John works 4 days per week, so in 2 weeks, he would work 8 days. He drives 10 miles round trip per day, which means he drives a total of 80 miles in 2 weeks (10 miles * 8 days). His car gets 20 miles to the gallon, so he would need 4 gallons of gas to cover the 80 miles (80 miles / 20 miles per gallon). Gas is $2.50 per gallon, so he would spend a total of $10.00 on gasoline (4 gallons * $2.50 per gallon). Therefore, the correct answer is $10.00.

100 divided by 0= _________.
Correct Answer
C. Undefined

Jack goes fishing on Saturday and catches 32 fish. On Sunday, he catches 1/4 the amount of fish he catches on Saturday. On Monday, he catches 1/2 the fish he caught on Saturday and Sunday combined. How many fish did he catch on Monday?
Correct Answer
D. 20
Explanation
On Saturday, Jack catches 32 fish. On Sunday, he catches 1/4 of the amount he caught on Saturday, which is 32/4 = 8 fish. Therefore, the total number of fish he caught on Saturday and Sunday combined is 32 + 8 = 40 fish. On Monday, he catches 1/2 of the fish he caught on Saturday and Sunday combined, which is 40/2 = 20 fish. Therefore, Jack catches 20 fish on Monday.

Ned has a fruit stand. Normally he sells apples for 40 cents a piece, but today he has apples on sale for 5 for $ 1. There are no limits on quantity. How much money would you have saved if you had bought 16 apples at the sale price?
Correct Answer
A. $3.20
Explanation
If you bought 16 apples at the sale price of 5 for $1, you would have spent $3.20. This can be calculated by dividing 16 by 5 to determine the number of sets of 5 apples you can buy, which is 3 with a remainder of 1. The 3 sets of 5 apples would cost $3, and the additional apple would cost $0.20. Therefore, the total amount saved would be $3.20.
