Equivalent fractions
6/8= n/12
find the missing number. give me the steps so i can understand it for future problems.

Well, 6/8 can be simplified: divide the numerator and denominator by 2, then your simplified fraction is 3/4. Now, multiply straight across: 4 times what=12? 3 does. So, you do the same thing to the numerator, because whatever you do to the denominator must be done to the numerator, and same reversed. 3*3=9, so the answer to this is 9/12!!

The length of what is left would be 1 1/2 feet long.
