The set shows the absolute values of a set of rational numbers in increasing order.

{0.4, 1, 2
1
2
, 4, 5.3, 7, 9.8}

can you determine the order of the rational numbers themselves? explain why.

a) yes, it is possible to determine the order of the rational numbers because we know the size of the rational numbers.
b) no, it is not possible to determine the order of the rational numbers because we only know the signs of the rational numbers.
c) no, it is not possible to determine the order of the rational numbers because we do not know the signs of the rational numbers.
d) yes, it is possible to determine the order of the rational numbers because we know that all of the rational numbers are positive.
