The question is:
If the ones digit of a number greater than 1 is 0, what factor or factors must that number have?
a) 2 only
b) 5 only
c) 2 and 5
d) neither 2 or 5
I thought neither D as it would have to be a number such as 10. 10 + 10 = 20
10 + 10 + 10 = 30 leaving zero's in the ones place. Am I right? Please help. Thanks

It's C because if the number is greater than 1 and has a zero the ones place ex: 10, 20, 30... it's factors have to include 2 and 5.
