Answer:
17
Explanation:
So I just did
So 6 into 1 is zero, so you put a zero on top of the one (just to help you.) then u add the 1 next to the number 0 (in the number 102.) So 6 into 10 is 1 so u put the 1 on top of the zero in the number 102. Then you see how much you have left which is 4 so u add the 4 next to the 2 to make 42. Then you ask yourself how much is 6 into 42 which is 7. So your answer should be 17
I hope I helped you:)
