The four-digit numeral 3AA1 is divisible by 9. What digit does A represent?
Answered by Emily
I just substituted in numbers from 0-9 to see what the answer was. "3AA1 is divisible by 9" means that the problem 3AA1 divided by 9 will equal an integral number. So, once you substitute in numbers you'll find that 3,771 divided by 9 equals 419, so A = 7. Hope this makes sense!

i thought that a number divisible to 9 has to have the number's digit add up to 9, like 9, 18, 27, 36, 45, 63, 72, 81
