A living room has a length of 18.25 feet and a width of 12 1/2 feet. What would those dimensions be on the architectural drawings, if the scale of 1 ft = 1/4 inch is used? (your answers should be given in 16ths of an inch)

if 1 foot = 1/4 inch, then
18.25 feet = 1/4(18.25) or 4 9/16 inches
12.5 feet = 1/4(12.5) or 3 1/8 inches
Argghh! Go metric ! 
3/ 1/8 is not in 16th how do i get it to 16th

1/8 = 2/16

how would i find these with those answers :
How many square feet are there? square feet (ROUND to the nearest WHOLE foot)
If we added 10 % additional for waste, how many square feet should be ordered? 
I got 228 ft squared
and 251 feet should be ordered
Is this right 
area = length x width
= 18.25 x 12.5 = 228.125 square feet
or 228 square feet in whole numbers
10% of 228 square feet is 22.8 square feet
so the total is 228 + 23 = 251 square feet.
