Question

Edwina, Lexi and Luis plant a tree every 1/4 of a mile along the trail. Write and evaluate a división expression to find the number of trees they will plant. Show your work. Write your answer in simplest form

Answer 1

To calculate the number of trees planted, divide the total length of the trail by 1/4 mile, or multiply by 4. This will give the number of trees in simplest form once the trail length is known.

Step-by-step explanation:

To find the number of trees Edwina, Lexi, and Luis will plant along the trail, we need to divide the total length of the trail (in miles) by the distance between each tree (1/4 mile). Say the length of the trail is 'L' miles, the division expression will be L / (1/4). To evaluate this expression, remember that dividing by a fraction is the same as multiplying by its reciprocal. So the expression becomes L x 4, which gives the total number of trees planted along the trail. Without the specific length of the trail, we cannot calculate an exact number of trees. However, this formula helps us find the answer in simplest form once 'L' is known.

Answer 2

Let m be the number of miles. We must find out how many 1/4-mile pieces are in their distance. That means we take m and divide it by 1/4:
m ÷ 1/4 = m/1 ÷ 1/4 = m/1 * 4/1 = 4m/1 = 4m.
