Each whole is two halves, so eight wholes are sixteen halves. Adding one half makes the total seventeen halves. Reducing this, of course, is simply eight and one-half.
10 halves in 5 wholes.
5 wholes = ten halves plus one half = 11 halves

There are 16 halves in eight wholes.
5 x 2 = 10 halves
You can make 4 wholes from 8 halves.
When you have 11 halves, you can think of it as having 11 parts, each of which is half of a whole. To find out how many wholes that is, you would divide 11 by 2, since there are 2 halves in a whole. Therefore, 11 halves is equal to 5 wholes with 1 half remaining.
