Including 101: 101, 103, 107, 109, 113, 127, 131, 137, 139, 149. There are 10.
Numbers from 0 to 100 that are multiples of 10 are: 10, 20, 30, 40, 50, 60, 70, 80, 90, 100. That's ten numbers, so the fraction of numbers from 1 to 100 that are multiples of 10 is 10/100. In simplest form it is 1/10.
Numbers which are the factors of thirty and multiples of five are 5, 10, 15 and 30.
That's a null set. All multiples of 10 are even.
The numbers that are between 55 and 101 that are also multiples of 3, 10 and 15 are: 60, 75 and 90.
80.

There are no numbers between 67 and 113 which are multiples of 65.
There are three numbers between 10 and 50 which are divisible by both 3 and 5. All numbers that are multiples of 3 and 5 are the multiples of the lowest common multiples (lcm) of 3 and 5 which is 15. The multiples of 15 between 10 and 50 are {15, 30 and 45}, thus there are 3 numbers.
60 and 90
Multiples of 10 cannot be prime.
33 multiples of 3 10 multiples of 10 -3 multiples of both 40 total
10, 20, 30, 40, 50, 60, 70, 80, 90, 100
Just count the multiples of 6...
It is 80
Any multiple of 10 is also a multiple of 5, so all you need to do is find the multiples of 10. Those are the numbers that end with zero.
