Answer 1

Option C

Solution:

• Rational numbers can be expressed as a fraction in the form
  `\displaystyle(p)/(q)`, where p is the numerator and q is the denominator.
• Now, which numbers can and cannot be expressed as a fraction?
• First of all, can we express
  `√(12)` as a fraction? No, it's a surd.
• Can we express
  `\pi` as a fraction? No. Remember, pi is irrational. It has an infinite number of digits after the decimal point (same with √12)
• Can we express
  `-\displaystyle(3)/(7)` as a fraction? Sure. What's more, it's already a fraction.
• Can we express √7 as a fraction? No. It's also irrational, like √12 and π.
