Pressumably that refers to the fact that the number of decimals is finite (not infinite). For example, if you divide 1 / 8, you get a finite number of decimals:
0.125
It ends there. Any further decimal digits would be zero, and can be omitted. On the other hand, if you divide 1 / 3, you get:
0.33333...
The 3s continue indefinitely.

What is a decimal number which ends after a finite number of digits after the decimal point is called?
It is a terminating decimal.
What is a rational number in decimal form that has a finite number of digits after the decimal point?
I think it's a repeating decimal.
How is a decimal a rational number?
A decimal is a rational number if:* It terminates - i.e., it has a finite number of decimal digits. * It doesn't terminate, but it repeats the same pattern over and over - possibly after a finite number of digits that are not included in the pattern. For example, 0.145145145145..., or 3.125252525...
Is .625 a terminating or repeating decimal?
.625 is a terminating decimal. A decimal is considered terminating if it has a finite number of digits after the decimal point. In the case of .625, there are only three digits after the decimal point, making it a terminating decimal.
Is 2.1245 rational?
Yes, because it has a finite decimal expansion.
