Question

What is the multiplicative inverse of 2 1/2?

A) 2/3
B) 2/5
C)2

Answer 1

Answer: B 2/5

Step-by-step explanation: Convert the mixed number 2 1/2 into an improper fraction first by multiplying the denominator (2) by the whole number part (2)and add the numerator (1) to get the new numerator. Place the new numerator (5) over the old denominator (2). And now inverse means opposite, so just flip it.

Finally: 5/2 inverse= 2/5

Answer 2

If you get rid of the whole number in that fraction, you will have 3/2.
So the opposite of that would be 2/3.
I believe the answer is 2/3.
