Half of 27
Half of 27 is 13½
27 ÷ 2 = 13½
27 is an odd number, so it does not split into two equal whole groups — 13½ means 13 and a half.
How to find half of 27
- 1Half means splitting 27 into 2 equal groups, so work out 27 ÷ 2.
- 227 is an odd number, so it will not split into two equal whole groups — one group always ends up with one more.
- 3Put 13 in each group and there is 1 left over. Split that last one in half too.
- 4So half of 27 is 13½ — 13 and a half. The even numbers either side, 26 and 28, halve to 13 and 14.
Check it: put the two halves back together and you get 13½ + 13½ = 27.
