Question

What is an equation in which 10 is a divisor?

Answer 1

I'm not really sure what you mean

Answer 2

10 is a divisor of n if
10k=n where k is an integer

Answer 3

How would I explain that to a 4th grader? lol

Answer 4

I know how you would explain how an equation can have a divisor.

Answer 5

Now if you want to explain what I said
You might say something like any number number than can be divided by 10 with no remainder THAT that number has 10 as a divisor...
Or you might want to talk about the positive multiples of 10 first...
1(10)=10
2(10)=20
3(10)=30
4(10)=40
....
314(10)=3140
All of these products are divisible by 10
