The steps of locating a proper fraction $\dfrac{a}{b}$ is given in jumbled form as follows:

1) Move a step on the right of 0
2) Locate the fraction $\dfrac{a}{b}$ at the point where you stop.
3) Draw a number line and locate integers on it.
4) Divide the space between 0 and 1 in 0 equal parts.
 Which of the following is the last step while locating $\dfrac{a}{b}$?
A) 1
B) 2
C) 3
D) 4

Hint:
Try to locate any proper fraction between 0 and 1. While following the steps unjumble the steps.

Complete step by step solution:
We need to follow the steps given here, that way it is easy to find the proper fraction.
So, the steps of locating a proper fraction $\dfrac{a}{b}$ are as follows:

1) Draw a number line and locate integers on it.
2) Divide the space between 0 to 1 into b equal parts.
3) Move a step on the right of o.
4) Locate the fraction $\dfrac{a}{b}$ at the point where you stop.
Thereby using these steps on the number line one can find out $\dfrac{a}{b}$ on a number line.
So, now if we do the same steps and come up with any answer, we get a proper fraction.
Now according to the question, the step which is last in finding the proper fraction is the second step i.e.
Locate the fraction $\dfrac{a}{b}$ at the point where you stop.

Note:
In this type of question thought process plays an important role. We should also have good knowledge of the number line. It’s a line in which we can represent all the real numbers. we will have to first solve the steps by looking in the question and then place the correct step in the correct places.
