What is the difference, please explain..!!

A pair of shoes is normally priced at $37. What will be the sale price if a 25% sales discount is offered?

I would assume i reduce $37 by 25%, i.e 37/1.25 = $29.60

However the answer is $37 x 0.75 = $27.75.

What is the difference in arising to the two unique solutions?
