Question

replace* by a digit to make the number exactly divisible by 9. 91739*19

please understand me clearly ​

Answer 1

Step-by-step explanation:

Numbers are divisible by nine only when the sum of the digits of the number is divisible by nine.

so,

91739*19 is divisible by 9

then,

9+1+7+3+9+*+1+9 is also divisible by 9

39+* is divisible by 9

In order for it to be divisible by nine, six must be added to it.

* = 6.
