Example: Check to see if 203 is divisible by 7. 1  double the last digit: 3 x 2 = 6. 2  subtract that from the rest of the number: 20 - 6 = 14. 3  check to see if the difference is divisible by 7: 14 is divisible by 7, therefore 203 is also divisible by 7.he number is divisible by both 2 and 3. 6. To find out if a number is divisible by seven, take the last digit, double it, and subtract it from the rest of the number. If you get an answer divisible by 7 (including zero), then the original number is divisible by seven.
The aim of this book is to help Muslims who have an addict in their family through better understanding of addiction and the role the family plays in recovery, not only for the addict but for themselves as well. Sadly today the Muslim community has its share of drug and alcohol problems.
Research has established that some of the risk for addiction to both drugs and alcohol is inherited. Children of alcoholics are 50 to 60 percent more likely to develop alcohol use disorders than people in the general population (4).Similarly, children of parents who abuse illicit drugs may be 45 to 79 percent more likely to do so themselves than the general public (5â7).This suggests that some of the risk factors for alcohol and other drug use are rooted in genetics, though studies of specific families have not proven a genetic contribution.imilarly, children of parents who abuse illicit drugs may be 45 to 79 percent more likely to do so themselves than the general public (5â7).
