30 is a multiple of 5
Further explanation:
A multiple is a number that divides the given number completely.
We have to find the multiple of 5 from given numbers.
For this purpose we have to write multiples of 5 first,
Multiples of 5 are:

We can see that out of all given numbers only 30 is a multiple of 5.
Similarly we can divide each number by 5, the numbers which are completely divided by 5 are multiples of 5
So,
66/5 =13.2
30/5 =6
29/5= 5.8
