Answer 2

Answer:

To check if a number is evenly divisible by 7: Take the last digit of the number, double it Then subtract the result from the rest of the number If the resulting number is evenly divisible by 7, so is the original number.

Step-by-step explanation:

10822

last digit is 2 double it =4. now 1082-4=1078

last digit is 8 double it=16 now 107-16=91

last digit is 1 double it =2 now 9-2=7

so it is Divisible by 7

10822/7=1546
