It isn't clear what you want to calculate. Add fractions? Multiply them? Convert fraction to decimal? Decimal to fraction? The details of the calculations, of course, vary depending on what you want to calculate.
You calculate the coordinates using a fraction!
The same as you calculate the fraction of anything. For example, a fifth of an hour is one part out of five equal parts of a whole hour.

Of course! Without decimals, you couldn't calculate percentages or fractions. Decimals allow you to break a number up. A decimal is basically a fraction, and when you calculate fraction adding, subtraction, multiplication, and division, sometimes it is easier to calculate a fraction by first changing it to a decimal instead.
Set up a fraction, so divide.
calculate the mole fraction of benzene in solution containing 30% by mass in carbon tetra chlorid
0.1176470588235294 = 1,176,470,588,235,294/10,000,000,000,000,000 = 588,235,294,117,647/5,000,000,000,000,000
It's basically 22/7 as a fraction
In order to calculate fractions, you need to know two numbers ... the part and the whole. Since you didn't say 7 oranges out of whatever the total is, we can't calculate a fraction.
The line that separates the top number (numerator) from the bottom number (denominator) of a fraction can be called a dividing line - since this is what is happening in the sum itself to calculate the fraction.
