Question

6a839859 is divisible by 9 find the value of a​

Answer 1

Answer:

6

Step-by-step explanation:

divisibility rule for 9 is that sum of all digits should be divisible by 9

(6+a+8+3+9+8+5+9) = 48+a

48 + a should be divisible by 9

45<48+a<54

then number should be grater than 45 because if we take 45 as the nearest number then the value of a becomes negative

so we will take 54 as the nearest number

48+a=54

a=54-48= 6

Answer 2

here , 6a839859 is given

or,6a839859=9

or,5039154a=9

hence,a=0.0000018
