What is the multiplicative inverse of 2 1/2?

OpenStudy (study_together):

Dividing by a fraction is the same as multiplying by its reciprocal. Remember: All numbers except 0 have a multiplicative inverse. The inverse of 5 is 1/5. But 0 has no inverse because you can't multiply any number by it to get 1.

@Study_together so is it still 2 1/2 because the 1/2 would be com 2?

OpenStudy (anonymous):

or just 2?

OpenStudy (study_together):

I suppose yeah

OpenStudy (anonymous):

@Study_together okay thanks
