by: Karin

For this problem, we must remember that slope is:
rise/run.

Therefore the ratio is:
215/2640

Now we must divide in order to change this ratio (fraction) to a decimal. Then we can change a decimal to a percent.

215/2640 = .0814

Now to change the decimal to a percent, you must multiply the decimal by 100 or move the decimal point two places to the right.

.0814 * 100 = 8.14

Therefore, the grade of the hill is 8.1%.

I hope this helps,
Karin
