3 of anything is almost always less than 5 of the same thing.
That's true for cows, rocks, trees, fish, salt-shakers, and babies.
I can't think of any object where it wouldn't be true.
Why wouldn't it be true for tenths ?

Let me say it another way:

No.  3/10  is less than  5/10 .
3 is always less than 5 in fractions and whole numbers. Think of it as 3 parts of ten squares are shaded and 5 out of ten squares shades, which it more. The answer is 3/10 is greater than 5/10
