Question

which number is bigger 5.09 or 5.1

Answer 1

5.1 is bigger than 5.09. If a decimal is a single number, add a 0 to the end.

Answer 2

You can take note of the fact that zeros after decimal point are trimmed.

The comparison is:

$5.09 < 5.1$ (5.1 is bigger than 5.09)

What happens to the zeroes which are on the rightmost side after a  decimal?

We don't write zeros which are rightmost after the decimal point. This is same as  we don't write zeros in the leftmost side of any number. Both are because we assume their presence.

Thus, 100 = 0100 = 00100 and so on.

And 5.1 = 5.10 = 5.100 and so on.

For given number, we have:

5.09 and 5.1 = 5.10

Now it must be visible that after 5, in the first digit there is .09 and in second there is .10

Since .10 is positive and .09 is positive, thus we have .10 bigger.

$.10 > .09\\5 + 0.10 > 5 + 0.09\\5.10 > 5.09\\5.1 > 5.09$

Thus, $5.09 < 5.1$ (5.1 is bigger than 5.09)
