What least whole number should be added to 532869 to make it divisible...
To determine the least whole number that should be added to 532869 to make it divisible by 9, we need to understand the divisibility rule for 9.
The divisibility rule for 9 states that a number is divisible by 9 if the sum of its digits is divisible by 9.
Let's find the sum of the digits in 532869:
5 + 3 + 2 + 8 + 6 + 9 = 33
Since the sum of the digits, 33, is not divisible by 9, we need to add a number to make it divisible by 9. To find this number, we need to determine the remainder when 33 is divided by 9.
When 33 is divided by 9, we get a remainder of 6. This means that we need to add 6 more to 33 to make it divisible by 9.
Therefore, the least whole number that should be added to 532869 to make it divisible by 9 is 6.
In the given options, option C (3) is incorrect as adding 3 to 532869 would result in a sum of 36, which is divisible by 9. The correct answer is option D (6).
