A decimal number is simply a way of representing a number in such a way that the place value of each digit is ten times that of the digit to its right. A decimal representation does not require a decimal point. So the required decimal representation is 3100, exactly as in the question.
Three thousand, one hundred.
3100 is an integer which can be expressed as a fraction as 3100/1.
-3100 is an integer, not a fraction. You could write it in the form of a rational fraction as -3100/1.
3100 hundred-thousandths in standard form is 3.1 × 10-2
3100, like any integer, can be written as a fraction in simplest form by putting it over 1.
The decimal form of 7.73 times 10 to the negative third power is 0.00773
3/100 is in its simplest form.
4.05 times 10 to the third power = 40.5
A decimal form is a representation of a number in a way such that the place value of each digit is ten times that of the digit to its right. So 37 is a decimal form. As are 0.048 and 39.029
use the invisible decimal at the end and move it 2 times to the left!
9/50 times 2 = 18/100 an the decimal is 0.18
