You can make 3 wholes
1
3 x 2 = 6 halves
8
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
20
There are 16 halves in eight wholes.
5 x 2 = 10 halves
You can make 4 wholes from 8 halves.
12
14
Six whole halves. Each whole has two halves making it, 6(wholes)x2(#of halves in whole)= 12. 12 halves in 6 wholes.
3 / 0.5 = 6
5 + 1/2. need to see how many halves are in 5. there are 2 halves in one, i.e. 2/2 so 5 halves = (5x2)/2. This = 10/2, + 1/2 = 11/2
2 ÷ 1/2 = 2 x 2/1 = 4 Alternatively: 1 whole is 2 halves → 2 wholes = 2 x 2 halves = 4 halves.
