Answer:
Assuming Q is q, q = 12. 1/3 is a fraction since it is a ratio of two whole numbers.
Explanation:
For this problem, we need to understand two things. (1) q is the unknown variable of this equation. (2) The definition of a fraction is a "numerical quantity that is not a whole number" -Oxford Dictionary which can also be stated mathematically as a ratio of two whole numbers.
First, let's explain why 1/3 is a fraction. In the numerator, we have the whole number 1, and in the denominator, we have the whole number 3. Mathematically, 1/3 is a fraction since it is a ratio of two whole numbers. Alternatively, we can say it's a non-whole numerical quantity. In this case, 0.33 repeating.
Second, let's solve for our unknown variable q:
1/3 ( q + 3 ) = 5
1/3 ( q + 3 ) * 3 = 5 * 3
q + 3 = 5 * 3
q + 3 = 15
q + 3 - 3 = 15 - 3
q = 15 - 3
q = 12
Hence, the value of q is 12.
