Question

f) If 345x is a multiple of 3 where x is a digit. Write all the possible value of x so that given number is divisible by 3.​

Answer 1

Answer:

many value can be possible like

0, 3, 6, 9

Answer 2

Answer:

344 x = divisible by 3

Step-by-step explanation:

Let's take X = 1

3451 = ( Divisibility rule of 3 )

3+ 4 + 5 + 1 = 13 that is not divisible by 3

that means 1 is not the value of X Now let's take X = 3 = ( Divisibility rule of 3 )

3+ 4+5+3 = 15 is divisible by 3

that means 3453. is divisible by

3 . X = 3 is correct

Let's take X = 6 = ( Divisibility rule of 3 )

3+4+5+6= 18 . that is divisible by

3 that means 3456 is divisible by

3 so X = 6 is correct

Let's take X = 9 = ( Divisibility rule of 3 )

3+ 4 + 5 + 9 = 21 that is

divisible by 3 that means 3459

is divisible by 3 . So X= 9 ☑️

We cannot take X = 10 bcz only this is 2 digit no.

and the value is only once place that is X

So the possible value of X is = 3, 6 ,9

Hope it will help you
