You can put this solution on YOUR website! Dividing by a number is the same as multiplying by its inverse (if it has one -- 0 doesn't).
You have 9.8 divided by .57
.57 means 57 parts of 100, or 57/100
The inverse of 57/100 is easy to find. It equals 100/57.
So 9.8 / .57 = 9.8 * 100/57.
Do the math.
