Question

which of the two rational numbers is Greater - 7.12 or 5.12 with solution

Answer 1

5.12 is greater than -7.12

Answer 2

7.12 is smaller than 5.12
Since
-712/100 and 512/100 in rational form.

We know that 0 is smaller than 1
therefore -1 will be smaller than 0 as we go towards left side of number line.
Thus negative integers are smaller than 0 and 0 is smaller than all positive integers.
Now since -712/100 is negative rational number and 512/100 is positive.
Therefore 512/100 will be greater.
Thus 5.12 is greater.
