One half is just 1÷2 which is 0.5, add the 1 makes 1.5 1 + 1/2 = 1.5 1.6 has an extra 0.1, making it greater than 1.6 > 1.5
One and a half = 1.5, so 1.6 is more than 1.5. It's very trivial question.
1.6 is greater than one and a half (1.5). We can determine this by comparing their decimal values on a number line. Since 1.6 is to the right of 1.5, it is indeed more than one and a half.
