any decimal that terminates can be changed into a fraction by dividing the digits to the right of the decimal by 1 followed by the same number of 0s.

For example, 2.12345 has 5 digits after the decimal. So, you can change it to a proper fraction by dividing 12345/100000 and then adding the 2, or
12345
2 ---------
100000


That number can then be simplified to
2469
2 ---------
20000


by dividing both the top (numerator) and bottom (denominator) by 5.
