448 miles.
12.5x=100*56

Let X = total distance to drive; then
12 1/2% of X = 56 miles or .125 X = 56
X = 56 / .125 = 448 miles

12.5% is 1/8 so if 56 is 1/8 then 56 x 8 = total distance = 448 miles

12.5% is 1/8 of the distance so you multiply 56 by 8 or 56 X 8 = 448 miles. Consider that an early xmas present.

448 miles.
12½ % = 0.125 so if 12½ % of the total equals 56 miles, then: 0.125x = 56 miles and x = 8 * 56 miles = 448 miles.

Use a proportion:
12.5/56=87.5/x
(87.5% is the amount he hasn't driven)
Cross multiply
87.5(56)=12.5x
4900=12.5x
x=392
This is the amount he has NOT driven.
Add this number to the amount he has driven to get the total distance.
392 + 56 = 448 miles

56 = .125x since 56 is equal to 12.5% of the total
56/.125 = x just divide 56 by .125 to get the answer

12 1/2% = 0.125
x*.125 = 56
x = 56/.125 = 448 mi
