A road repair crew spread 9/10 of a ton of gravel evenly over 3 feet of road. How many tons of gravel did they spread on each foot of road?

If 9/10 tons of gravel got spread over 3 feet, then how much gravel is on each foot? Well, it's a ratio.

9/10 tons : 3 ft

So, we divide each side of the ratio by 3.

3/10 tons : 1 ft.

So, that 3/10 tons of gravel on each foot of road.
