If a third of six is three what would be half of twenty?

Answer 1

First of all, "a third of six" is not three, it is two...and half of twenty is ten. However, if by some mathematical gimmickry, a third of six were three then, by extension, half of twenty would be fifteen.

Answer 2

A third of six is two; three is half of six. To make three equal a third of six; add 2+1 together to equal 3. One(1)is half of two(2).

Half of twenty is ten. Add half of ten, which is five, to that and the answer is 15.

Just as the adjustment for the "unreal" fraction equivalents was made for the first part of this math riddle, it must also be applied to the second part to get the correct answer.

Try this:

If a third of six is three, what must a fourth of twenty be?

Answer 3

If a third of six is three, it means that 6 divided by 3 equals 2. Therefore, half of twenty would be 20 divided by 2, which equals 10.
