Question

Which numbers are positive rational numbers? Select all that apply.

A. 0.01
B. 5/12
C. 0
D. 4/3
E. 0/7
F. 9

Answer 1

These are all rational numbers, since they are either decimal number with finitely many decimal digits, fractions, or integers.

Also, they are all greater than or equal to zero, because there are no negative numbers.

So, if by "positive" you mean strictly positive, then number A, B, D, and F are positive rational numbers.

If by "positive" you mean "non-negative", then all these numbers are positive rational numbers.

Answer 2

All numbers are positive rational number.

0.01, 5/12, 0, 4/3, 0/7 and 9

Explanation:

Positive rational number :

Every positive number is rational number.

If the numerator and denominator are positive and negative integers it is called rational number.

(A). 0.01

This is the decimal number.

It can be written

`0.01=(1)/(100)`

Here, Numerator and denominator are positive

This is the rational number.

(B). 5/12

Here, Numerator and denominator are positive

This is the rational number.

(C). 0

It is the special rational number.

(D). 4/3

Here, Numerator and denominator are positive

This is the rational number.

(E). 0/7

It can be written in p/q where, q ≠0

It is a rational number.

(F). 9

It is a positive integer

It is a rational number.

Hence, This is the required solution.
