Make small
- D.
None of the above
Correct Answer
A. SimplifyExplanation
The term "simplify" means to reduce or make something smaller.

Which is NOT the correct way to say a ratio?
- A.
1:4
- B.
1 to 4
- C.
1 out of 4

One fourth
Correct Answer
D. One fourthExplanation
The phrase "one fourth" is not the correct way to express a ratio. Ratios are typically expressed using the format "a:b" or "a to b". "One fourth" is a fraction that represents a proportion, but it is not a ratio. Ratios compare two quantities and indicate the relationship between them, while "one fourth" simply represents a fraction or a part of a whole.Rate this question:

Which ratio is equivalent to 3:4?
- A.
9:12
- B.
6:12
- C.
12:9
- D.
None of the above
Correct Answer
A. 9:12Explanation
The ratio 9:12 is equivalent to 3:4 because both ratios can be simplified to the same value. To simplify the ratio 9:12, we can divide both numbers by their greatest common divisor, which is 3. Dividing 9 by 3 gives us 3, and dividing 12 by 3 gives us 4. Therefore, the simplified ratio is 3:4, which is equivalent to 9:12.Rate this question:

- C.
8:35
- D.
12:53
Correct Answer
C. 8:35Explanation
The ratio 24:105 can be simplified to the lowest terms by dividing both numbers by their greatest common divisor, which is 3. When we divide 24 by 3, we get 8, and when we divide 105 by 3, we get 35. Therefore, the ratio 24:105 in lowest terms is 8:35.Rate this question:

Review: Percent means out of...
- A.
1
- B.
10
- C.
100
- D.
1,000
Correct Answer
C. 100Explanation
Percent means out of 100. It is a way of expressing a portion or a fraction of a whole based on a scale of 100. For example, if something is 50%, it means it is half of the whole or half of 100. Similarly, if something is 100%, it means it is the entire whole or the whole 100. Therefore, the correct answer is 100 because percent refers to a value out of 100.Rate this question:
