Answer 2

The value of d is 9 for which 5456d is divisible by 18.

Step-by-step explanation:

To find : The value of the digit d for which 5456d is divisible by 18 ?

Solution :

Divisibility of 18,

A number is divisible by 18 if the sum of its digits is divisible by 9.

Now, first we sum the digits in the number

$5456d=5+4+5+6+d=20+d$

Put the value of d from 0-9 to check whether it is divisible by 9 or not.

For n=0, 20+0=20 not divisible by 9.

For n=1, 20+1=21 not divisible by 9.

For n=2, 20+2=22 not divisible by 9.

For n=3, 20+3=23 not divisible by 9.

For n=4, 20+4=24 not divisible by 9.

For n=5, 20+5=25 not divisible by 9.

For n=6, 20+6=26 not divisible by 9.

For n=7, 20+7=27 is divisible by 9.

Therefore, the value of d is 9 for which 5456d is divisible by 18.
