Rational Numbers

When we add the fractions to the Whole Numbers, we obtain the Rational Numbers, Q.
We represent them in the straight line too. For example, to represent 3/5:

- We draw a line from zero.

- We draw 5 marks at equal
distance with a compass.

- We connect the last mark
with 1 and draw the parallel lines.

Exercise: Represent these numbers in the number line: -7,  5,  1/5,  -2/3,  7/3,  3/2,  -9/5
