graphing fractions

Let us learn about graphing fractions


The term 'fraction defines a number that is being used to describe a part of a group & while writing it student can use the term denominator & numerator. Nominator is used to write the number that is above the line & denominator is used for the number that is below the line. Best example: If you write the term ½ you can say that the term is being written in terms of fraction & the digit '1' is known as the numerator while '2' is known as denominator.
How to graph fractions on a graph?
The same way student would graph numbers which are not fractions.
SAMPLE:
Graph 1/2 & 3/4 on the real number line.
<------(-2)------(-1)--------(0)------(1)-------(2)---->
Obviously, where would student put fractions 1/2 & 3/4?
The fractions would easily fit between 0 & 1, right?
The same applies to points on a graph.
SAMPLE:
Graph (2, 3/4) & (0, 1/2) on the xy-plane?

How would student graph these points?
For (2, 3/4), student travel 2 units to the right on the x-axis
& 3/4 units UP on the y-axis & plot the point there.
For (0, 1/2), student would NOT travel on the x-axis because of ZERO but student would need to travel 1/2 units UP on the y-axis and plot the point there.

In our next blog we shall learn about earth elements paint I hope the above explanation was useful.Keep reading and leave your comments.
