Half of 17
Half of 17 is 8½
17 ÷ 2 = 8½
17 is an odd number, so it does not split into two equal whole groups — 8½ means 8 and a half.
How to find half of 17
- 1Half means splitting 17 into 2 equal groups, so work out 17 ÷ 2.
- 217 is an odd number, so it will not split into two equal whole groups — one group always ends up with one more.
- 3Put 8 in each group and there is 1 left over. Split that last one in half too.
- 4So half of 17 is 8½ — 8 and a half. The even numbers either side, 16 and 18, halve to 8 and 9.
Check it: put the two halves back together and you get 8½ + 8½ = 17.
