Answer 1

Divide the numerator by the denominator.

I'll be glad to check your answer.

Answer 2

all fractions whose denominator (in lowest terms) contains only powers of 2 and 5 terminate.
Any other factor in the bottom produces a repeating decimal.
So, your numerator can be anything that does not have a factor of 3 to cancel the 3 in 15.

Answer 3

15
