Using divisibility tests,determine if a) 852 is divisible by 6 ? b) 1080 is divisible by 9 ? c) 6699 is divisible by 11 ? d) 85496 is divisible by 8 ?

Answer»

Step-by-step EXPLANATION:a) divisibility by 6 = divisibility by 2 and 3852 / 2 = 426852 / 3 = 284as it is divisible by 2,3;  852 is divisible by 6.b) divisibility by 9 = divisibility by 31080 / 3 = 360as 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 = 0even 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 8496 / 8 = 62as last 3 digits is divisible by 8;  85496  is divisible by 9.
