2.9 is fairly easy to convert to a fraction if you understand some basic principles of decimals and the base ten number system.
Numbers are structured in the following columns:
...1000's 100's 10's 1's 10ths 100ths 1000ths...
So for the number 1234.567,
The 1000's column contains the digit 1
The 100's column contains the digit 2
The 10's column contains the digit 3
The 1's column contains the digit 4
The 10ths column contains the digit 5
The 100ths column contains the digit 6
The 1000ths column contains the digit 7
And for the number 12.6 (or 0012.600)
The 1000's column contains the digit 0
The 100's column contains the digit 0
The 10's column contains the digit 1
The 1's column contains the digit 2
The 10ths column contains the digit 6
The 100ths column contains the digit 0
The 1000ths column contains the digit 0
----------------
One 10th can be written as the fraction 1/10
As the number 2.9 contains 9 in the 10ths column, we have 0.9 = 9/10 from that column.
In addition to the 0.9, we also have 2.0
If we move 2 down to the 10ths column, we get 2 = 20/10
Adding the two parts together, we get the fraction 29/10.
Or by skipping the 2, we get the form of 2 9/10
