No, a square root doesn't have to be a whole number. The square root of 2.25 is 1.5. It could be said that most square roots are not whole numbers. Take just the first few integers (counting numbers). Find the square roots of the numbers 1 through 10 and you'll find three of the numbers have whole number square roots (1, 4 and 9). The other seven don't. For the numbers 11 through 20, there is only 1 number with a whole number square root (16).
To write "one hundred forty-seven and nine hundred twenty-three millionths" in numbers, you would write it as 147.000923. The whole number part is 147, and the decimal part is 0.000923, which represents nine hundred twenty-three millionths.
Very rarely. Square roots are only whole numbers for perfect squares.
No. Square roots of whole numbers that don't result in whole numbers (e.g. the square root of 64 is 8), are considered to be "Irrational Numbers".
All whole numbers between 1 and 400 (=20 square).
Numbers with square roots that are whole numbers

Rational numbers whose square roots are whole numbers are themselves whole numbers. They are called square numbers, e.g. 1, 4, 9, 16, 25 and so on.
Every whole number
To write "one hundred forty-seven and nine hundred twenty-three millionths" in numbers, you would write it as 147.000923. The whole number part is 147, and the decimal part is 0.000923, which represents nine hundred twenty-three millionths.

All whole numbers between 1 and 400 (=20 square).
Among the whole numbers, these are:149162536496481100
The square root of 31 falls between the whole numbers 5 and 6.
The square root of 110 is an irrational number and so it cannot be any two whole numbers.
