We need to evaluate the value of fraction
.
We also given j=12.
In order to evaluate the value of fraction
, we need to plug j=12.
Plugging j=12, we get

We have 12 in numerator and 4 in denominator.
We always divide top number by bottom number.
So, we need to divide 12 by 4.
On dividing 12 by 4 we get 3.
Therefore,
