Arithmetic Reasoning
In my ASVAB prep course, I focus on the topic of fractions in my classes that cover Arithmetic Reasoning. In adding and subtracting fractions, it is essential to find a common denominator. You do not need to find a common denominator when multiplying fractions. My book, The ASVAB Tutor’s Arithmetic Reasoning Study Guide reviews the necessary steps for performing the four basic operations with fractions: addition, subtraction, multiplication, and division.
Yesterday I presented an Arithmetic Reasoning question.
The skill is multiplication of fractions.
The question is:
Solve
5/6 x 2/4 =
A. 5/12
B. 1/2
C. 7/24
D. 5/6
To multiply fractions, there is no need to find a common denominator.
It simply involves multiplying the numerators and multiplying the denominators.
5/6 x 2/4 = 10/24
10/24 can be reduced.
Since 10 and 24 are both even numbers, they can both be divided by 2.
10/24 = 5/12
The final answer is 5/12
The correct answer is Choice A. 5/12
