  • 2. 

    Putting a fraction or ratio in LOWEST TERMS     

    • Simplify

    • Reduce

    • Make small

    • None of the above

    Correct Answer
    A. Simplify
    Explanation
    The correct answer is "simplify" because when a fraction or ratio is in its lowest terms, it means that it has been simplified or reduced as much as possible. This involves dividing both the numerator and denominator by their greatest common divisor to make the fraction or ratio smaller and easier to work with. Therefore, "simplify" is the best explanation for the given correct answer.

    Rate this question:

  • 3. 

    Equivalent

    • Various

    • Total

    • Sum

    • Equal

    Correct Answer
    A. Equal
    Explanation
    The word "equal" means that two or more things are the same in quantity, size, value, or importance. It suggests that there is no difference or distinction between the things being compared. In the context of the given options, "equal" is the most appropriate choice as it best conveys the idea of things being identical or having the same value.

  • 4. 

    Review:  Percent means out of...

    • 1

    • 10

    • 100

    • 1,000

    Correct Answer
    A. 100
    Explanation
    Percent means "out of 100". It is a way of expressing a fraction or a portion of a whole in terms of 100 equal parts. For example, 50 percent means 50 out of 100, or half of the whole. Therefore, the correct answer is 100 because percent is based on dividing a value by 100.

    Rate this question:

  • 5. 

    Finding how much ONE quantity would be           (per gallon, per ounce, per person)

    • Proportion

    • Ratio

    • Unit

    • Unit rate

    Correct Answer
    A. Unit rate
    Explanation
    The term "unit rate" refers to the rate at which one quantity is compared to one unit of another quantity. It is used to find out how much one quantity would be in terms of a specific unit, such as per gallon, per ounce, or per person. It is a ratio that helps in comparing different quantities on a common scale and is often used in calculations and conversions.

    Rate this question:

  • 6. 

            comparing two different variables:  miles to gallons, sandwiches to people, etc.

    • Proportion

    • Rate

    • Ratio

    • Unit

    Correct Answer
    A. Rate
    Explanation
    The term "rate" refers to the comparison between two different variables, such as miles to gallons or sandwiches to people. It represents how one quantity changes in relation to another. A rate is often expressed as a ratio, but it specifically emphasizes the comparison between different units or measurements. Therefore, "rate" is the most appropriate term to describe the given scenario.

    Rate this question:

  • 7. 

    Which is NOT the correct way to say a ratio?

    • 1:4

    • 1 to 4

    • 1 out of 4

    • One fourth

    Correct Answer
    A. One fourth
    Explanation
    The phrase "one fourth" is not the correct way to express a ratio. Ratios are typically expressed using numbers separated by a colon (1:4), the word "to" (1 to 4), or the phrase "out of" (1 out of 4). However, "one fourth" is a fraction, not a ratio.

    Rate this question:

  • 8. 

    Two ratios that are equivalent.

    • Proportion

    • Ratio

    • Unit rate

    • Rate

    Correct Answer
    A. Proportion
    Explanation
    A proportion is a statement that two ratios are equivalent. It compares two ratios and states that they are equal to each other. In other words, a proportion shows that the relationship between the two ratios remains the same. Therefore, the answer "proportion" is correct because it accurately describes the concept of two ratios being equivalent.

    Rate this question:

  • 9. 

    Which ratio is equivalent to 3:4?

    • 9:12

    • 6:12

    • 12:9

    • None of the above

    Correct Answer
    A. 9:12
    Explanation
    The ratio 9:12 is equivalent to 3:4 because both ratios can be simplified to the same fraction. When we divide both 9 and 12 by their greatest common divisor, which is 3, we get 3:4. Therefore, 9:12 is equivalent to 3:4.

    Rate this question:

  • 10. 

    What is the ratio 24:105 in lowest terms?

    • 2:23

    • 24:105

    • 8:35

    • 12:53

    Correct Answer
    A. 8:35
    Explanation
    The ratio 24:105 can be simplified by dividing both numbers by their greatest common divisor, which is 3. After simplification, the ratio becomes 8:35.
