Let's look in ~ our decimal areas again. 2 is in the tenths place, so we have actually two-tenths.
Next is the hundredths place. In this example, 5 is in the hundredths place, so we have five-hundredths.

So we'll review 0.25 together twenty five-hundredths.
This is simply another method of creating 25/100.
To figure out how plenty of hundredths we had actually total, we could have included these numbers: two-tenths and five-hundredths.
