Answer:
The answer is C.
Explanation:
1/2 x 4/1 = ?
We begin by multiplying the numerators:
1 x 4 = 4
And then we multiply the denominators:
2 x 1 = 2
The answer has a numerator of 4 and a denominator of 2. In other words:
1 x 4/2 x 1 =4/2
This fraction can be reduced to lowest terms:
4 ÷ 2/2 ÷ 2 =2/1 = 2
