To reduce a fraction divide the numerator and the denominator by their greatest common factor, GCF. ... The numerator and the denominator of the fraction are coprime numbers (no common prime factors, GCF = 1), the fraction cannot be reduced (simplified): irreducible fraction.
Answer:
C. 18:30
Step-by-step explanation:
Divide the y values (games played) by the x values (games won) to find your ratio. The ratio across each of these pairs is 1.666667...
Using the ratio provided, 18:30, divide 30 by 18.
30/18 = 1.666667...
It's a match!
Therefore, the answer is C. 18:30
