Each time you move the decimal, the value changes by 10.
What pattern did you observe each time you flipped the sediments
Three quarters is equivalent to three-fourths of a whole, which can be expressed as 0.75 in decimal form or 75% in percentage terms. In terms of time, three quarters of an hour is 45 minutes.

If you repeat the pattern, adding one more zero every time, then no. To qualify as a "repeating decimal", the same digits have to repeat over and over.
A positive integer is a whole number or a counting number that is greater than 0. "Decimal" simply means that the place value of each digit is ten time that of the digit to its right. A decimal number does not require a decimal point.

22. There are four one fourths in 1. So four time 5 is 20 and there are 2 one fourths in one half. So that is 20 plus 2 is 22.
Add 3 each time
As of 17 October 2011, the answer is 10 trillion = 1013. While there are repeats of short patterns from time to time, the decimal representation does not - and cannot - settle into a repeating pattern.
