Reduce 72/108 to its lowest terms.

  1. 72/108
  2. 1/3
  3. 6/9
  4. 2/3

Explanation:

Find the factors of the numerator and denominator. 72/100 = 36×2/36×3
The 36 in the numerator and the 36 in the denominator cancel out. The simplified fraction, or the reduced fraction is 2/3, the correct answer.

What is the value of x if 4x + 3 = 23?

  1. 4
  2. 6
  3. 5
  4. 3

Answer(s): C

Explanation:

Try plugging each of the given choices as x in the expression 4x + 3 and see which one will give the value of 23. If we take x = 5, we have 5x4 equals 20, and 20 + 3 equals 23. Clearly, 5 is the correct answer.
Another method would be to solve algebraically: 4x + 3 = 23; isolate the term with the x variable: 4x = 23 − 3 = 20; we then have: 4x = 20; divide both sides of the equation by 4 to get the value of x: 4x/4=20/4; this gives us the value of x:x = 5.



What is 104?

  1. 10,000
  2. 10
  3. 100
  4. 100,000

Answer(s): A

Explanation:

The expression 104 means that the base, 10, is raised to the power of 4 or multiplied by itself 4 times. Thus, 10 × 10 × 10 × 10 = 10,000.
