A term for a number that has no decimal or fraction is called a whole number.

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 provided the number is a decimal fraction, it can be represented as a mixed number. If it is a decimal integer then it is not a mixed number and it makes no sense to try to represent it as one.

Since pi is an irrational number it is impossible to represent the exact quantity as a decimal; you can only give and approximate value. However, if you write a fraction that includes the symbol for pi, you are giving an exact quantity.

A decimal number is one in which the place value of each digit is ten times the place value of the digit to its right. (... , thousands, hundreds, tens, units, tenths, hundredths, ... ) A decimal point is used to separate the units from the tenths. If a number in decimal form has non-zero digits after the decimal point then it is a decimal fraction. [There is one esoteric exception: if the decimal point is followed by an infinite string of 9s, then it is not a decimal fraction.] Thus 37.6 is a decimal fraction 0.6 is a decimal fraction 0.00000063 is a decimal fraction 37 is not a decimal fraction. 37.0 is not a decimal fraction. 37.999... recurring is no a decimal fraction [it is in fact = 38].

It represents the value of the variable m.

The value of 2.4 in a decimal fraction is: 22/5

"Pi" is an irrational number. No series of digits can represent its value exactly, whether written as a fraction or as a decimal. The decimal can be extended to any number of significant figures, no matter how large, and never ends.

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 8, exactly as in the question. Also, 8 is an integer, not a fraction so there is no sensible way to represent it as a fraction. However, if you must, you could write is as 8/1.

It represents the value of the variable m.

0.91 is a fraction. It is a fraction in decimal form rather than in the form of a ratio. However, that does not stop it being a fraction. And, since it is a decimal fraction, there is not another simpler decimal form. Its equivalent, in rational form, is 91/100 which cannot be simplified. Also, the absolute value of the given fraction is less than 1. There is, therefore, no sensible way to represent it as a mixed fraction.

The value of the 5 as a fraction is 1/2 or as a decimal is 0.5

It means that you find a decimal number that has the same value as the fraction - or often a value that is close, since most fractions cannot be expressed exactly with a terminating decimal. Just divide the numerator by the denominator, to get an equivalent decimal.

The value is the same, the whole number ( to the left of the decimal point ) is the same, but the fraction of 1 ( to the right of the decimal point) can be expressed as either a fraction or a decimal depending on its use, so for example: 1.375 is the same as 1 3/8
