Question

TRY THESE
Check the divisibility of the following numbers by 3.
1. 108
2. 616
3. 294
4. 432
5. 9
EXERCISE 1.2
. If 21y5 is a multiple of 9, where y is a digit, what is the value of
y?
• If3125 is a multiple of 9, where z is a digit, what is the value of z?
You will find that there are two answers for the last problem. Why is this so
If 24x is a multiple of 3, where x is a digit, what is the value of x?
(Since 24x is a multiple of 3, its sum of digits 6+x is a multiple of 3; so 6+
of these numbers: 0,3,6,9,12,15, 18.... But since x is a digit, it can only
6+x=6 or 9 or 12 or 15. Therefore, x= 0 or 3 or 6 or 9. Thus, x can have
four different values.)​
