What is (1/3 + 1/3)?
- A.
9-Feb
- B.
3-Feb
- C.
9-Jan
- D.
6-Feb
Correct Answer
B. 3-FebExplanation
The correct answer is 3-Feb because when you add 1/3 and 1/3, you get 2/3. The numerator stays the same, but the denominator doubles. So, 2/3 can be written as 2 divided by 3, which is equal to 0.666... When converted to a date format, this is equivalent to February 3rd.Rate this question:

If a jar has 4 blue, 12 yellow, and 6 red marbles, what is the probability of choosing a red marble?
- A.
22-Jun
- B.
10-Jun
- C.
12-Jun
- D.
6
Correct Answer
A. 22-JunExplanation
The answer "22-Jun" is incorrect and does not provide a valid explanation. The question asks for the probability of choosing a red marble from a jar that contains 4 blue, 12 yellow, and 6 red marbles. To find the probability, we need to divide the number of red marbles by the total number of marbles in the jar. Therefore, the correct answer should be 6 (the number of red marbles) divided by 22 (the total number of marbles in the jar), which equals 6/22 or 3/11.Rate this question:

What is the perimeter of a rectangle that has a length of 10 feet and a width of 5 feet?
- A.
30 Square Feet
- B.
50 Feet
- C.
20 Square Feet
- D.
30 Feet
Correct Answer
D. 30 FeetExplanation
The perimeter of a rectangle is calculated by adding up all the sides. In this case, the length of the rectangle is 10 feet and the width is 5 feet. To find the perimeter, we add up the lengths of all four sides, which are two lengths and two widths. So, the perimeter is 10 + 10 + 5 + 5 = 30 feet.Rate this question:

What must be added to 3/5 in order to get 1?
- A.
5-Feb
- B.
5-Mar
- C.
2-May
- D.
3-May
Correct Answer
A. 5-FebExplanation
To find what must be added to 3/5 in order to get 1, we need to subtract 3/5 from 1. This can be done by finding a common denominator for both fractions, which in this case is 5. So, 1 can be written as 5/5. Subtracting 3/5 from 5/5 gives us 2/5. Therefore, 2/5 must be added to 3/5 in order to get 1.Rate this question:

Which is the best estimate for 47 + 39?
- A.
100
- B.
90
- C.
120
- D.
110
Correct Answer
B. 90Explanation
The best estimate for 47 + 39 would be 90. This is because when estimating, we can round both numbers to the nearest tens place. 47 can be rounded down to 40, and 39 can be rounded up to 40. Adding these rounded numbers together gives us 80, which is closest to the answer of 90.Rate this question:

8,847
- B.
8,874
- C.
8,748
- D.
8,784
Correct Answer
B. 8,874Explanation
To find the largest 4-digit number, we need to place the highest value digit in the thousands place. Since the highest value digit is 8, we place it in the thousands place. Then, we arrange the remaining digits (4, 7, and 8) in descending order to get the largest possible number. Therefore, the largest 4-digit number we can make is 8,874.Rate this question:
