Answer 1

2/5

Step-by-step explanation:

First, we need to write the number 2 1/2 as a fraction. This number is equal to

`2(1)/(2)=((2*2)+1)/(2)=(4+1)/(2)=(5)/(2)`

Then, the multiplicative inverse of 2 1/2 is the multiplicative inverse of 5/2. The multiplicative inverse of a fraction can be calculated as 1 divided by the fraction, so

`1/(5)/(2)=1*(2)/(5)=(2)/(5)`

Therefore, the multiplicative inverse of 2 1/2 is 2/5
