Given:
Number 15#794
To Find:
The value of #
Solution:
- Here, we will apply the divisibility test of 9 to find the value of #.
- The sum of a number's digits must be divisible by 9 in order for it to be divisible by 9.
- For the given number 15#794 we have to find the value of # for which it is divisible by 9.
So, we will add the digits first
15#794
1+ 5 +# +7 +9+4
=26+#
As we know that 26 is not divisible by 9
So, let us first assign # = 1
Then,
26+ 1 = 27
27 is divisible by 9
Hence, the smallest number that must be assigned to # is 1.
