515 in an integer, not a fraction!
5.15 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, being a decimal, there is no simpler form. Its rational equivalent is 515/100 which can be simplified to 5 3/20.
There are 1.609344 kilometres in one mile. Therefore, rounded to two decimal places, 515 kilometres is equal to 515/1.609344 = 320.01 miles.
0.4 as a fraction and decimal
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].
515 is an integer and not a fraction. However, it can be expressed in rational form as 515/1 which cannot be simplified.

515 is an integer and so there is not really a sensible way of writing it as a fraction or mixed number.
To write 5.15 as a fraction, you first need to determine the place value of the decimal. In this case, the 1 in 5.15 is in the hundredths place. Therefore, you can write 5.15 as 515/100, which can be simplified to 103/20 by dividing both the numerator and denominator by 5.
5/15 = 1/3
515/1 is one possible answer.
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 515, exactly as in the question.
There are 1760 yards in one mile. Therefore, rounded to two decimal places, 515 yards is equal to 515/1760 = 0.29 miles.
There are 1.609344 kilometres in one mile. Therefore, rounded to two decimal places, 515 kilometres is equal to 515/1.609344 = 320.01 miles.
a decimal fraction means a fraction that changes into a decimal or a decimal that changes into a farction
The number 5.15 has 2 spaces past the decimal (5.15). Therefore multiply it by 10^2 power, or 100. Then take that number, (515) and put it over the number you multiplied it by (100). You get 515/100 or 5 15/100 or 5 3/20
