Assuming that zero cannot be used for the first digit then this can be selected from numbers 1 - 9 (9 choices), and the 2nd, 3rd and 4th digits from 0 - 9 (10 choices). The total number of different ways is : 9 x 10 x 10 x 10 = 9000.
9
You can write a ratio three ways. Ex: 2/9, 2 to 9 or 2:9
2/3, 4/6
A can be 0 or 9.

1 x 81 3 x 27 9 x 9
9
3 to the power of 4 9 to the power of 2 81 to the power of 1 I'm on this problem in my notebook too ;)

Nine elevenths, 9/11, 0.8181 repeating, 81.82%
9 to the 2nd power (92) 3 to the 4th power (34)
How many different ways can we arrange 9 objects taken 3 at a time?
They are as follows:- 3.1 3.14 3.141 3.1415 3.14159 3.141592 3.1415926 3.14159265 3.141592654 Or as a fraction 22/7 approximately Note that there are billions and billions of ways to write out pi as number because it is an irrational number.
They are: 3/5 = 6/10 = 9/15
