**Anonymous**, Wednesday, April 29, 2009 at 10:24pmIt is 70 unless you are actually dividing by 2 instead of one half.

30 / (1/2) = 30 * 2 = 60

60 + 10 = 70

I don't understand how your friend got 12.

**Sammy**, Wednesday, April 29, 2009 at 10:24pmi think it is 25. Both your friend and you are wrong because when you divide 30 by half you get 15.So 15+10=25.

**Erin**, Wednesday, April 29, 2009 at 10:32pmYour not dividing IN half, but BY half. I did it the way of using fractions. Because half is .5 or 1/2. I have no idea how he got 12 either!
