to get from a decimal number to a percentage - I move the decimal two places to the right -> which would be 4.97% (rounded to two decimal places)
So then would my shrinkage have been approximately 5% ??

You're calculating the shrinkage in terms of the area.
Your method was correct, but the numbers not: ;-)
77 divided by 1512 = 5.1% (it's expressed as a %, not inches).
So the area of the washed fabric is 5.1% smaller than the unwashed fabric.
or
77 INCHES sqin = 5.1% of the size of the unwashed fabric
If you want to do see the % shrinkage in each direction (width vs. length), then you'd just use those numbers.
So it would be 1 divided by 36 (2.7%) or 1 divided by 42 (2.4%) (respectively for W or L shrinkage).
With these numbers, the shrinkage by length and width now total the overall shrinkage.
I guess there are fabrics that might shrink substantially more one way than the other....I'm not sure if LQS cotton is one of them
