People tend to speak more quietly in restaurants than they do when they are having an ordinary conversation restaurant conversation is about 45 db. if ordinary conversation is 100 times greater than restaurant conversation, how loud is ordinary conversation?

A loud ordinary conversation following the supplied information in the question is about 4500 dB. But, in the official decibel system measure a loud conversation does not overcome 100 dB.

Explanation:

Using the supplied data of the exercise, we say that in a restaurant conversation the value is 45 dB. If we multiply this by 100 we will have a value for a laud ordinary conversation.

45×100 = 4500 dB.

but as I mentioned in the answer, in the official decibel system measure a loud conversation between 2 man reaches a maximal of 100 dB.
