Can decimals be divided by decimals?

Answer 1

Yes.

Assuming these decimals are real numbers, you can divide them by each other.

For example:

If somebody asks you to find out the radius of a circle that is 3.5m2 then you would have to use the area formula for a circle (area = πr2).

So you have

3.5 = πr2

r2 = 3.5/π

See how we have a decimal (3.5) divided by another decimal (π). We know that the radius must exist because there is no way that a circle with an area of 3.5m2 is impossible.

A decimal is just way of representing a number. The form in which it is written doesn't define what can be done with it.
