Answer:
Step-by-step explanation:
a) divisibility by 6 = divisibility by 2 and 3
852 / 2 = 426
852 / 3 = 284
as it is divisible by 2,3; 852 is divisible by 6.
b) divisibility by 9 = divisibility by 3
1080 / 3 = 360
as it is divisible by 3; 852 is divisible by 9.
c) divisibility by 11= Take the alternating sum of the digits in the number, read from left to right.
6-6 = 9-9 = 0
even if zero is answer it is divisible by 11.
6699 is divisible by 11.
d) divisibility by 8= If the last three digits of a whole number are divisible by 8
496 / 8 = 62
as last 3 digits is divisible by 8; 85496 is divisible by 9.
