There are three numbers a, b, c, where a &gt; b and b &gt;c. Describe the positions of the numbers on a number line.
AfilCa [17]
In maths, the “>” sign means “greater than”, or “bigger than.” If we say A > B, that means (in English) “A is bigger than B.”
So, if A > B and B > C:
A is bigger than B, and B is bigger than C.

So the smallest would be C, since both A and B are bigger. Next is B, and biggest is A.

That is the order they would be in a number line: C - B - A
