12.5? or "what". Did you mean "Divide thirty by half and add ten?"? Then the answer would be seventy.
25 but what do you mean when you say one-half? 15perhaps or something else seing as this is a brain teaser.
The answer is 70.
If you divide 30 by 0.5 you get 60 then add 10 you get 70.
The trick here is that people read it as 'divide 30 IN half' and end up with a total of 25.
30 divided by .5 plus 10 equals 70 70
30 divided by 5 = 6 + 10 = 16

Half is the same thing as .5 so you divide 30 by .5 and you get 60 then you add 10 so it is 70. TADA!!!
