If 5432 * 7 is divisible by 9, then the digit in place of * is ?Options0169

The divisibility rule of 9 states that a number is divisible by 9 if the sum of its digits is divisible by 9.

Let's apply this rule to the given problem:

5 + 4 + 3 + 2 + 7 = 21.

Now, we need to find a digit that we can add to 21 to make the total divisible by 9.

The options are 0, 1, 6, and 9.

Adding 0 to 21 gives 21, which is not divisible by 9.

Adding 1 to 21 gives 22, which is not divisible by 9.

Adding 6 to 21 gives 27, which is divisible by 9.

Adding 9 to 21 gives 30, which is not divisible by 9.

Therefore, the digit in place of * is 6.
