Question 365076
I'm having problems on divisibilty on my homework. The exact directions are: Test each number for divisibilty by 2,3,5,9 or 10.   Here is ONE problem from my homework. 1) 126  This is the number you have to test. Thanks


126:
by 2, yes since last digit is even
by 3, 1 + 2 + 6 = 9 and 9 is divisible by 3 so yes
by 5, 6 is not divisible by 5 so no
by 9, 126/3 = 42, 4 + 2 = 6 and 6 is divisible by 3 so yes
by 10, the last digit is not 0 so no
