Answer:
0
Explanation:
if you were to multiply any whole number by ten all you would have to do is move the decimal a place over to the right.
for example:
9 x 10 = 90
(whole number) (ten) ( 9.0 move the decimal once, because there is only one zero in the number ten, and then the outcome is 90)
This rule works with any number, not just one digit numbers.
14x10=140
56x10=560
178x10=1780
1249x10=12490
and all these numbers end with zero (0).
hope this helped.
