How to find half of any number
Multiply the number by 5 (five), then move it a decimal point to the left.
6 (six) times 5 is 30, for instance, so put the decimal point in between the 3 and the 0. That would just be 3!
Divide each number by 2 if you have two even digits.
Divide the digits individually, then put them together. That may make a complicated process much simpler.
