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.

There are 16 halves in eight wholes.
There are 6 of them because 6/2 = 3
10 halves in 5 wholes.
You can make 4 wholes from 8 halves.

5 wholes = ten halves plus one half = 11 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.
2 ÷ 1/2 = 2 x 2/1 = 4 Alternatively: 1 whole is 2 halves → 2 wholes = 2 x 2 halves = 4 halves.
Six wholes can be split into 12 halves
