Answer:
Any number bigger than 2/3
Step-by-step explanation:
btw, I didn't see the options but here's the explanation
When you multiply by a part of a whole, a fraction, you are getting smaller. When you multiply by a number bigger than one, your product gets bigger. So, any number bigger than 2/3 works just fine
Remember that multiples are numbers that can be divided by a number without a remainder so in this case you could add 15 by 15 to find what number in this set is a multiple of 15.




Therefore your answer is "60."
Hope this helps.
