Answer 2

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.
