Numbers become a repeating decimal when dividing by ANY whole number, except when (if the division, expressed as a fraction, is in simplest terms) the denominator has no prime factors other than 2 and 5.The reason for this is related to the fact that our decimal system is base 10, and 10 is made up of the factors 2 and 5. Any denominator with other factors cannot be exactly expressed as a terminating decimal. That includes denominators 3, 6, 7, 9, 11, 12, 13, 14, 15, 17, 18, 19, 21, etc.

Some do, some don't. 27 divided by 9 equals 3. You can also get repeating decimals with other divisors.

An irrational number can become rational by dropping a few decimal places. Ans 2. An irrational number can produce a rational by being truncated as desired. The square root of 2 is often truncated to 1.414, and is useful in all sorts of technologies at that accuracy. However, it is no longer the square root of 2 ! It is often a useful approximation, but to a mathematician it is a queer duck.
Well, honey, an integer is a whole number without any decimal or fraction. So, 0.9 is not an integer because it has a decimal point and a fraction part. It's as simple as that, darling.
Whenever you have a number to the negative power, the number would become a fraction so that the power could be positive: 8-4 = 1/84 which results in 1/4096 = 2.4414x10-4 (decimal form)
I'd start by figuring 1% of 11 million, and then tripling that answer. To get 1% of anything, move the decimal two places to the left. So 1,000,000. will become a "1" followed by 4 zeros, not 6 zeros. That's 10,000. Ten thousand. Triple it = thirty thousand.
