Which of the following is correct?

  1. 4/8 = 8/17
  2. 5/12 = 15/24
  3. 3/4 = 9/12
  4. 2/3 = 7/10

Answer(s): C

Explanation:

Multiply 3/4 by 3/3 to get 9/12. 3/4 × 3/3 = 9/12.
We have introduced a fraction 3/3 which is actually equal to 1. It’s like 3/4 × 1=3/4; by introducing 1, we’re not changing the equation.
We just used 3/3 instead of 1. Therefore, 3/4 × 1=9/12; 3/4 × 3/3 = 9/12; 9/12 = 9/12.



Which number is in the hundredths place in 0.5983?

  1. 5
  2. 3
  3. 8
  4. 9

Answer(s): D

Explanation:

The spot immediately to the right of the decimal is the tenths place (in this problem, 5), followed by the hundredths place (9), thousandths place (8), and ten thousandths (3).



What is 4 3/8 + 2 2/7?

  1. 6 37/56
  2. 6 5/15
  3. 6 27/56
  4. 8 6/56

Answer(s): A

Explanation:

6 37/56 is the correct answer because the whole numbers (4 and 2) are first added together to get 6, and then a common denominator must be found for the fractions. 8 multiplied by 7 equals 56, which will be the common denominator in this equation.
Whatever is done to the denominator must also be done to the numerator, so: 3/8 = 21/56 and 2/7 = 16/56
Since the denominators are now the same, you can just add the numerators: 21/56 + 16/56 = 37/56
Add the whole number, 6, from the beginning and you have 6 37/56.



Which of these is correct?

  1. 4/6 = 10/12
  2. 5/9 = 12/28
  3. 6/8 = 12/16
  4. 3/4 = 15/25

Answer(s): C

Explanation:

Note: This question requires you to tell if 2 fractions are equivalent, regardless if either is in lowest terms. Multiply 6/8 by 2/2 to get 12/16

6/8 × 2/2 = 12/16
By doing this, we’re not changing the value of the equation because 2/2 is also equal to 1 and multiplying a number by 1 does not change the value of a number.

Therefore:
6/8 × 1 = 12/16
6/8 × 2/2 = 12/16
12/16 = 12/16

This does not work with any of the other answer choices; the two fractions in each are simply not equal.
