Middle: 2.5 ft
Right: 4,375 ft
Left: 1,875 ft
Step-by-step explanation:
We know that a tree in the middle is 2.5 feet tall.
Now the tree on the left measures 3/4 of the tree in the middle, therefore:
2.5 * 3/4 = 1.875
Which means that the tree on the left is 1.875 feet tall.
Finally the tree on the right 1 3/4, which would be 1.75 times the tree in the middle, therefore:
2.5 * 1.75 = 4.375
Therefore the tree on the right is 4.375 feet tall.
