No. A decimal is a way of representing a quantity so that the place value of each digit is ten times the place value of the number to its right. So the opposite would be to find a way not to represent a number?! What is the point of that?
you put a number with a decimal
The number after the decimal.
To find percents from a normal number, you will multiply the normal number by 100, the opposite as going from a percent to a decimal. Therefore, 7.2*100 is equal to 720%.
The number of decimal places in the product is the SUM of the decimal places in the multiplicands.
Divide the numerator (the top number) by the denominator (the bottom number) and you will get a decimal number.
In whole numbers, a decimal follows the number. Example, in the number 7, the decimal is after it, 7.0 The decimal is not visible, but it is there.
It is a requirement to find a decimal representation which has only a finite number of digits after the decimal point.
A decimal becase a decimal can be any fraction
The nearest decimal number is 2.25 since, for with other decimal number, it is possible to find infinitely man decimal numbers which are nearer to 2.25
The question is based on a false premise: the opposite of a decimal is not a whole. A decimal is simply a way of representing a number is such a way that the place value of each digit is ten times that of the digit to its right. Therefore 4 is a decimal, 2.75 is a decimal. There are different ways of defining opposite. The additive opposites of the two numbers are -4 and -2.75 so one of them is a whole number, the other is not. The multiplicative opposites are 0.25 and 0.3636... so neither of them are whole.
To find the percentage from a decimal number is simply move the decimal point two places to the right. The procedure is the same no matter what the number and so there is no difference and so there is no value which is easiest.
