Question 1)

Which of the following do not represent the rational number?

a) 3/5 b) 15 c) 4/0 d) none of above

Answer:

c) 4/0

Step-by-step explanation:

A rational number is a number that can be expressed as p/q (a non-zero denominator q).

In the given options a) 3/5 and b) 15 or 15/1 represent the rational number. While option c) 4/0 don't represent the rational number. As said above rational number expressed in the form p/q with non zero denominator.

Therefore, the correct option is option c) 4/0.

Question 2)

Which of the following is an example of a positive rational?

a) -2/7 b) 3/-5 c) -4/-9 d) none of the above

Answer:

c) -4/-9

Step-by-step explanation:

Positive rational means numerator and denominator both are postive or both negative; in short overall positive value. But in given options are values are negative.

We know that-

• Fraction of (+) and (+) is (+)
• Fraction of (-) and (-) is (+)
• Fraction of (+) and (-) is (-)
• Fraction of (-) and (+) is (-)

Therefore, -4/-9 can be written as 4/9.

Hence, the postive rational is option c) -4/-9.
