Tyesha needs 17 3/4 feet of wood for a project. She has lengths of wood that are
7 1/2 feet, 5.25 feet, and 6 3/4 feet long. Does
Tyesha have enough wood for her project?

No, Tyesha doesn't have enough wood for her project.

Step-by-step explanation:

Let the length of woods she has be a, b, and c respectively.

Given the following data;

Length of wood required = 17¾ ft.

Length, a = 7½ ft.

Length, b = 5.25 = 5¼ ft.

Length, c = 6¾ ft.

To determine if she has enough wood;

Length of wood required should be equal to the length of wood available.

Therefore, we would sum up all the length of woods she has.

Total length = a + b + c

Substituting into the equation, we have;

Total length = 7½ + 5¼ + 6¾

We would add the whole numbers together.

Total length = (7 + 5 + 6) + (½ + ¼ + ¾)

Note: ¼ + ¾ = 4/4 = 1

Total length = 18 + (½ + 1)

Total length = 18 + ½ + 1

Total length = 19½ ft

19½ ≠ 17¾

Therefore, the length of wood Tyesha has isn't equal to the length of wood required.
