The country recreation department cleared a 3/4 mile long walking trail in Washington Park. There will be a small sign every 1/12 mile along the trail, including at the beginning and end of the trail. How many signs are needed

We are given " The country recreation department cleared a 3/4 mile long walking trail in Washington Park."

Therefore total distance = 3/4 miles.

"There will be a small sign every 1/12 mile along the trail, including at the beginning and end of the trail. "

Distance of small sign = 1/12 mile.

We need to find the number of signs in 3/4 miles each of 1/12 miles.

In order to find the number of signs, we need to divide total distance by distance of a small sign.

3/4 : 1/12

= 3/4 * 12/1 = 3 * 3

= 9 signs.

Therefore, 9 signs are needed.
