To find the missing digit that makes the number 3,71_ divisible by 9, we can apply the rule that states a number is divisible by 9 if the sum of its digits is divisible by 9.
Step 1: Calculate the sum of the known digits: 3 + 7 + 1 = 11.
Step 2: Find the missing digit y that, when added to 11, produces a sum that is divisible by 9.
To determine the value of y, we need to find the smallest positive integer that, when added to 11, makes the sum divisible by 9. Starting with 1, we can increment the value of y until we find a suitable integer:
11 + 1 = 12 (not divisible by 9)
11 + 2 = 13 (not divisible by 9)
11 + 3 = 14 (not divisible by 9)
11 + 4 = 15 (not divisible by 9)
11 + 5 = 16 (not divisible by 9)
11 + 6 = 17 (not divisible by 9)
11 + 7 = 18 (divisible by 9)
Therefore, the missing digit y that makes the number 3,71_ divisible by 9 is 7.
the digits must add to a multiple of 9
3+7+1 = 11, so
3717 = 413*9
