Question

Section D (Do as directed)
025)Find the smallest value of the unknown digit x such that the number will be divisible
by 3
(1)4526x
(2) 213x6
(3) 412x4​

Answer 1

Answer:

1) x = 1

2) x = 0

3) x = 1

Step-by-step explanation:

1) 4526x

To be divisible by 3, the sum of the digits should be divisible by 3

4 + 5 + 2 + 6 + x

= 17 + x

= 17 + 1

= 18, which is divisible by 3 and x = 1 is the smallest possible answer

2) 213x6

To be divisible by 3, the sum of the digits should be divisible by 3

2 + 1 + 3 + x + 6

= 12 + x

= 12 + 0

= 12, which is divisible by 3 and x = 0 is the smallest possible answer

3) 412x4

To be divisible by 3, the sum of the digits should be divisible by 3

4 + 1 + 2 + x + 4

= 11 + x

= 11 + 1

= 12, which is divisible by 3 and x = 1 is the smallest possible answer
