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!!!
The answer is 90. Dividing in half is also same as multiplying it by 2. Then you add 10, you'll get 90.
Seventy. 30 / .5 = 60; 60 + 10 = 70.

First, you ask what number the person is thinking of between one and ten.Then, you tell them to double it.Next, you tell them to add a number, specifically between one and ten and that can be split in half.Now, tell them to divide the number that is now in their head by 2.Now tell them to subtract their original number from the number they have now.The trick is, when you tell them to do #3, that automatically tells you that their number is half of what you told them to add. Hope this helps!
30 / 2 + 10 - 2 = 23

When you divide 30 by half, you are essentially dividing 30 by 0.5, which equals 60. Adding 10 to 60 gives you a final result of 70.
Seventy. 30 / .5 = 60; 60 + 10 = 70.
If you subtract five from ten you are left with five.You can subtract the sugar and add honey for this recipe if you prefer.
