Question

What is the least common denominator for this equation?

A. 9
B. 36
C. 36c
D. 12c

Answer 1

B

Explanation:

Though it is not obvious, the c belongs in the numberator, not the denominator.

So C and D are both wrong.

9: 3 * 3

3: 3

4:2 * 2

Lowest common denominator = 2 * 2 * 3 * 3

Lowest common denominator = 36

B
