.
10.5 - 82%2F3 = 101%2F2 - 82%2F3 =

= 21%2F2 - 26%2F3 =    (write the ratios with the common denominator, which is 6)

= %2821%2A3%29%2F6 - %2826%2A2%29%2F6 = 63%2F6 - 52%2F6 = 

= %2863-52%29%2F6 = 11%2F6 = 15%2F6.

You merely subtract 8 2/3 from 10 1/2...we get
10 1/2 - 8 2/3 =
10 3/6 - 8 4/6 =
(now borrowing we get)
9 9/6 - 8 4/6 =
1 5/6 lengths
