Lowest common Denominator ?

I was informed if you measure something that is for example 45 7/16 inch you should reduce the 7/16 by the lowest common denominator but what would that denominator be for 7/16. I can't divide a even number into both numbers?

Hi;

You can't reduce 7/16 it is already in lowest terms.

But, for example, 6/16 could be reduced to 3/8

Re: Lowest common Denominator ?

I understand because 2 can go into 6 and 16 but there is nothing that can go into both 7 and 16.  Alright thank you.  Excellent forum.
