One way of doing it would be do put smaller tick marks in between the larger tick marks for whole numbers. So if you want to represent, 1, then 1.25, 1.50, 1.75 then 2 on a number line, you could put a large tick mark with the number '1' above it, then 3 evenly space smaller tick marks, then another large tick mark with the number '2' above it. If you have enough room, you could write the decimal numbers above the smaller tick marks, too.

Write two fractions that the point on the number line represent
To convert a fraction to a decimal you need to divide the numerator (the number above the line) by the denominator (the number below the line). 11/20 = 0.55

It represents a number.
A proper fraction in which the denominator is a power of 10.
As a decimal, it is 4. This is an integer and there is not a sensible way to represent it as a mixed number.
