The answer is the third one. which is:
He made a computation error when he added 10.35+7.6
15/24
4 2/3=(4*3)+2/3=14/3
simply 15/24
15/3/24/3=5/8
refine
5/8*14/3
8 and 14 share a factor of 2
8/2=4
14/2=7
refine
5/4*7/3
5*7/4*3
35/12
convert to mixed number
35/12=2.11
2 11/12
the answer is 2 11/12
6xy in simplest form is simply 6 to the second power
Hope this helps!
The answer is fifteen yards
