Find the smallest digit d so that 437,d03 is divisible by 9.

ivann1987 [24]

9514 1404 393

Answer:

d = 1

Step-by-step explanation:

For the number to be divisible by 9, the sum of digits must be a multiple of 9. The sum of digits is ...

4 + 3 + 7 + d + 0 + 3 = 17 +d

The nearest multiple of 9 is 18, so we have ...

17 +d = 18

d = 18 -17 = 1

The value of d is 1.
