In this question the decimal except 5.0 because it is equal to 5 cannot be call an odd number also the fraction 3/2, except 6/2 because it is equal to 3. So 1, -1, 5.0 & 6/2 or 3

I had similar issues understanding the sentence. After reading it several times, I figured that he meant "all the decimals, except 5.0, are not odd".

Remember to use proper phrasing, so that your solution is easily understood.

First you look at the numbers. Integers are whole numbers that can either be positive or negative. Or can be zero. But if you look at the numbers you have numbers with decimals and fractions. All of them together are 4.
