Question

The height of a tree when planted is 1.1m. One year later the height of the tree is 1.9m. Calculate the percentage increase in the height of the tree over a year

Answer 1

The height of the tree has increased by 72% (72727273% to be exact).

The calculation to find that answer is the new height (1.9) divided by the old height (1.1).

1.9/1.1 = 1.72727273

The 1 in the answer is basically the original height, so you can ignore as we already know that the height has increased

Answer 2

72.7273%

Explanation:

Just divide 1.9/1.1 and get 1.7273 which is equal to around 72%
