Writing decimals as fractions

If you say the decimal right then it makes changing decimals into fractions easy. For example: 0.6 is equal to 6/10. If you want to put it into simplest form it would be 3/5. How you change a decimal that goes on and on is *the denominator will always be 9 and the numerator will be the number that is repeating in the decimal. But a terminating decimal (a decimal that doesn't repeat) does NOT have 9 as it's denominator it has a 10 as the denominator.
