Scientific notation is in the form: a * 10b.
We count the number of digits: 10. We know that the exponent is one less than the # of digits. Therefore it's going to be on the form: a * 109.
We get rid of all the trailing zeros, and put a period after the first digit: 1.205
So the # in scientific form is: 1.205 * 109.
