Answer: A
Step-by-step explanation:
change ratios to fractions: 15/6, 18/15, 12/8, 24/10
common denominator is 60 so new fractions become:
150/60, 72/60, 90/60, 144/60 - A has the most spice!
of course you could reduce the first set of fractions and choose a common denominator of 10. Either way the answer is the same.
