Replace the * with the smallest digit to make it divisible by 11

45*53

$\huge\tt\colorbox{pink}{Answer}$

So first we have to know the divisibility test of 11.

If the alternate numbers from right to left are added as in the above number

we will add 1+2+(no.we have to find=x)

3+x

And other alternate numbers as 7+3+4=14

So the rule is that when you subtract the first list of alternate numbers from the second list, the difference should be 0 or a multiple of 11.

So 3+x-14=0[As we have to find the smallest number]

3+x=14

x=14-3

x=11

Because the number is equal by 11 we will subtract 11 from the number.

11-11=0

Therefore the smallest number is 0.
