Question

is 6x5 is exactly divisible by 3 then the least value of x is​

Answer 1

Answer:

Step-by-step explanation:

the numer6x5 to be divisible bby 3 the condition is that the sum of numer should be a multiple of 3

there fore 6+x+5 is divisible by 3

thereforethe nearest multiple of 3 to 11+x is 12

therefore x=1

Answer 2

The divisibility rule of 3 :- If all the digits equal to a no. that is divisible by 3 then the whole no. is divisible by 3.

So 6+x+5 = any multiple of 3 but x should be a single digit.

11+x = 12 (the multiple of 3 nearest to 11)

x = 1

11+x = 15 ( next multiple )

x = 4

11+x = 18 (-do-)

x = 7.

11+x = 21 (-do-)

x = 10

but we have to take only single digits so this value is neglected.

so x can be equal to 1,4 and 7 ( we have not tried 0 because 11 is not a multiple of 3 )

Hope this helps if so plz mark as brainliest.
