Fractions for carpentry: wall height of 8′, a ¾″-thick hardwood finish floor,...
I am doing my carpentry homework and I am having trouble understanding a few of the math questions they have. Here is one of them:
A carpenter needs to calculate the correct length of the wall studs for a platform-frame construction. The building will have a finished floor-to-ceiling height of 8′, a ¾″-thick hardwood finish floor, ¾″ furring strips in the ceiling, and ½″ gypsum board on the ceiling. The combined thickness of the top plates and the sole plates is 4½″. What would be the correct stud length for this building?
A. 8′1″
B. 7′10½″
C. 7′8½″
D. 7′9½″
So, what I did was I added all the 3/4, 3/4, 1/2, and 4 1/2 which came up to 5 3/2. So next I add that together to make that 13/2. Then 92 5/8's I made an improper fraction, 741/8. This gave me the answer of 1. So, I am assuming that the answer is A. Unless I completely botched that up.
