    Change 4 2/5 to an improper fraction.

    • 20/5

    • 22/5

    • 4/25

    • 25/5

    Correct Answer
    A. 22/5
    Explanation
    To change a mixed number to an improper fraction, we multiply the whole number by the denominator and add the numerator. In this case, we multiply 4 by 5 and add 2 to get 22. The denominator remains the same, which is 5. Therefore, 4 2/5 can be written as the improper fraction 22/5.

    Solve for the variable.27 + n = 42

    • N = 69

    • N = 25

    • N = -15

    • N = 15

    Correct Answer
    A. N = 15
    Explanation
    To solve the equation 27 + n = 42, we need to isolate the variable n. We can do this by subtracting 27 from both sides of the equation. This gives us n = 42 - 27, which simplifies to n = 15. Therefore, the correct answer is n = 15.

    Are 8/9 and 24/27 equivalent?  

    • Yes

    • No

    Correct Answer
    A. Yes
    Explanation
    Two fractions are equivalent if they represent the same value. To determine if 8/9 and 24/27 are equivalent, we can simplify both fractions. The numerator and denominator of both fractions are divisible by 3, so we can simplify 8/9 to 8/9 and 24/27 to 8/9. Since both fractions simplify to the same value, 8/9 and 24/27 are indeed equivalent.

    • N= -3

    Correct Answer
    A. N = -4
    Explanation
    To solve the equation -32 = 8n, we need to isolate the variable n. We can do this by dividing both sides of the equation by 8. When we divide -32 by 8, we get -4. Therefore, the value of n that satisfies the equation is -4.

    Rate this question:

  • 10. 

    Solve for the variable.n/6 = 12

    • N = 72

    • N = -72

    • N = 2

    • N = -2

    Correct Answer
    A. N = 72
    Explanation
    To solve for the variable, we need to isolate it on one side of the equation. In this case, we have n divided by 6 equals 12. To get rid of the division, we can multiply both sides of the equation by 6. This cancels out the division on the left side, leaving us with n equals 72. Therefore, the correct answer is n = 72.
