Add 3/4 foot to 2/12 foot.  The LCD here is 12.

Thus, add 9/12 foot to 2/12 foot.  Answer:  11/12 foot.
 
 Are you sure you copied down that "2/12" correctly?  Note that 2/12 = 1/6

In this Problem you will be using Addition to solve for the answer
3/4 + 2/12
First make the denominators the same by multiplying.
4 can go into 12.
Multiply the numerator and denominator of 3/4 by 3
3 x 3= 9  4 x 3= 12
Problem is now: 9/12 + 2/12
add the numerators
Answer is: 11/12
