Reducing Fractions & Number Recongnition - Quiz


Questions and Answers
  • 1. 

    4/8 = 1/?

    • A.

      3

    • B.

      2

    • C.

      5

    Correct Answer
    B. 2
    Explanation
    To find the value of the missing number, we can simplify the fraction 4/8. Both the numerator and denominator are divisible by 4, so we can divide them both by 4 to get 1/2. Therefore, the missing number that completes the equation is 2.

    Rate this question:

  • 2. 

    6/8 = ?/16

    • A.

      3

    • B.

      8

    • C.

      12

    Correct Answer
    C. 12
    Explanation
    To find the missing value in the equation, we can cross multiply. Multiplying 6 by 16 gives us 96. So, the missing value should be a number that, when multiplied by 8, gives us 96. Dividing 96 by 8 gives us 12, which is the missing value in the equation. Therefore, the correct answer is 12.

    Rate this question:

  • 3. 

    6/8 = ?/4

    • A.

      12

    • B.

      8

    • C.

      3

    Correct Answer
    C. 3
    Explanation
    To solve this equation, we can cross multiply. So, multiplying 6 by 4 gives us 24, and multiplying 8 by ? gives us a result of ?. Since 24 divided by 8 equals 3, the missing number must be 3 in order for the equation to be balanced. Therefore, the correct answer is 3.

    Rate this question:

  • 4. 

    1/4 = ?/8

    • A.

      2

    • B.

      3

    • C.

      4

    Correct Answer
    A. 2
    Explanation
    The equation 1/4 = ?/8 can be solved by cross-multiplication. Multiplying 1 by 8 gives 8, and multiplying 4 by ? gives 4?. Therefore, 4? = 8. To find the value of ?, we divide both sides of the equation by 4, resulting in ? = 2.

    Rate this question:

  • 5. 

    10/16 = 5/?

    • A.

      8

    • B.

      4

    • C.

      7

    Correct Answer
    A. 8
    Explanation
    The equation 10/16 = 5/? can be solved by cross multiplying. Cross multiplying means multiplying the numerator of one fraction with the denominator of the other fraction. In this case, 10 multiplied by ? is equal to 5 multiplied by 16. Simplifying this equation gives us 10? = 80. Dividing both sides of the equation by 10 gives us ? = 8. Therefore, the missing value is 8.

    Rate this question:

  • 6. 

    5/16 = ?/16

    • A.

      5

    • B.

      10

    • C.

      1

    Correct Answer
    A. 5
    Explanation
    The given equation is asking for the missing number that, when divided by 16, would equal 5 divided by 16. To find this missing number, we can set up a proportion. Since the denominator is the same (16), we can compare the numerators: 5 equals the missing number. Therefore, the missing number is 5.

    Rate this question:

  • 7. 

    1 = ?/16

    • A.

      16

    • B.

      2

    • C.

      8

    Correct Answer
    A. 16
    Explanation
    The correct answer is 16 because when you divide any number by 16, the result is the same number. Therefore, dividing 1 by 16 equals 0.0625, which is equivalent to 16/16.

    Rate this question:

  • 8. 

    7/8 = ?/16

    • A.

      14

    • B.

      6

    • C.

      2

    Correct Answer
    A. 14
    Explanation
    To solve the equation 7/8 = ?/16, we can use the concept of proportions. Cross-multiplying, we get 8 times ? equals 7 times 16. Simplifying, we find that ? is equal to 14. Therefore, the missing number that satisfies the equation is 14.

    Rate this question:

  • 9. 

    1/4 = ?/16

    • A.

      8

    • B.

      2

    • C.

      4

    Correct Answer
    C. 4
    Explanation
    The given equation is 1/4 = ?/16. To solve this equation, we can cross multiply. Multiplying 1 and 16 gives us 16, and multiplying 4 and ? gives us 4?. Therefore, 4? = 16. Dividing both sides of the equation by 4 gives us ? = 4. So, the missing number that satisfies the equation is 4.

    Rate this question:

  • 10. 

    8/16 = ?/2

    • A.

      4

    • B.

      2

    • C.

      1

    Correct Answer
    C. 1
    Explanation
    In the given equation, 8/16 is equivalent to 1/2. Therefore, the missing value that makes the equation true is 1.
