I'd start by thinking how many possibilities there are, so how many 3 digit integers (whole numbers) are there?
Then i'd consider how many numbers in this range are divisable by 7, a simpler example which may help you get started would be how many numbers from 1 to 70 are divisable by 7 the answer is just 70/7 = 10.
Once you've found out how many numbers between the range are divisable by 7, find out what percentage is this amount to the original range?
I hope this helps (and i hope it's right
)
