Answer: They are both equivalent.
I don't see a multiplication table down below, but I get what you're trying to answer.
Step-by-step explanation:
8:14 and 24:42 are both the same as 8/14 and 24/42. Multiply both the denominator and numerator by 3 since that's how you solve equivalent ratios. If you try 1 and 2, they will not work. 8*3=24 and 14*3= 42, therefore 8:14.
I hope this helps
