Half of 33
Half of 33 is 16½
33 ÷ 2 = 16½
33 is an odd number, so it does not split into two equal whole groups — 16½ means 16 and a half.
How to find half of 33
- 1Half means splitting 33 into 2 equal groups, so work out 33 ÷ 2.
- 233 is an odd number, so it will not split into two equal whole groups — one group always ends up with one more.
- 3Put 16 in each group and there is 1 left over. Split that last one in half too.
- 4So half of 33 is 16½ — 16 and a half. The even numbers either side, 32 and 34, halve to 16 and 17.
Check it: put the two halves back together and you get 16½ + 16½ = 33.
