Answer:
The smallest four digit number that is divisible by 3,6,9 is 1062
Step-by-step explanation:
You just have to find their Divisibility Rules.
--------------------------------------------------------------------------------------------------
The Divisibility Rule of 3 is when the sum of the digits of a number is divisible by 3, then the number is divisible by 3.
Ex: The number 94113 is divisible by 3 because the sum of its digits 9+4+1+1+3=18 is divisible by 3.
---------------------------------------------------------------------------------------------------
The Divisibility Rule of 6 is when the number is BOTH divisible of 2 and 3.
Ex: The number 9630 is divisible by 6 because the last digit is divisible by 2 in 0,2,4,6,8 and the sum of its digits 9+6+3+0=18 is divisible of 3
The Divisibility Rule of 9 is also similar to The Divisibility Rule of 3. It only needs to be divisible by 9.
Ex: The number 51984 is divisible by 9 because the sum of its digits 5+1+9+8+4=27 is divisible by 9.
