The equation that can be used to support her claim that product of two rational numbers is always rational is; C: 1/3 * 9
<h3>How to Identify Rational Numbers?</h3>
A rational number is a number that is expressed as the ratio of two integers, where the denominator should not be equal to zero
Option A) The square root of 2 is an irrational number because it cannot be given as the ratio of two integers.
Option B) π is an irrational number because you can't write it down as a non-infinite decimal. Thus this option is incorrect.
Option C) 1/3 * 9 = 3. This can be used to support her claim that product of two rational numbers is always rational because both numbers on left and right can be given as the ratio of two integers.
Option D) The square root of 3 is an irrational number because it cannot be given as the ratio of two integers.

Answer:
c = 0
Step-by-step explanation:
There can only be one possibility to make this equation make sense. If we were to do any number greater than 0, the equation wouldn't work.
If c = 0
9(0) + 27 = 27
0 + 27 = 27
27 = 27 :)
If c = 1
9(1) + 27 = 27
9 + 27 = 27
36 ≠ 27 :(
