This math puzzle looks simple, but the phrase divided by half trips up a lot of people.
The expression is:
110 divided by half, plus 13
Dividing by one-half is the same as dividing by 0.5, which doubles the number:
110 ÷ 0.5 = 220
Now add 13:
220 + 13 = 233
So the correct answer is 233.
The most common mistake is treating “divided by half” as “divided by 2.” But those are not the same operation. Dividing by 0.5 makes the number twice as large.
Answer: 233.
