Answer:
B
Explanation:
A isn't right. A is the reciprocal of 125%
125% = 1.25 = 5/4.
1//5/4 = 4/5
B is correct because you are asked for a mixed number. 125% is (1 + 1/4) * 100. The point is that 1 1/4 is a mixed number.
C is right as far as it goes, but it is an improper fraction ( a fraction greater than 1)
D is also an improper fraction.
