Homework Help: Math

Posted by Liz on Wednesday, January 20, 2010 at 9:55am.

Can you please explain this to me.

The problem is 7/16 - 3/20

First I have to find the common denominator which would be 80

How does the 7/16 become 35/80 (where does the 35 come from)
How does the 3/20 become a 12/80 (Where does the 12 come from)

35/80 minus 12/80

answer 23/80
