Answer:

80 lemons

Step-by-step explanation:

Let x represent the amount of lemons that were on the tree.

We can use this to set up an equation:

$40\%x=32$

Note that percentages can also be written as that number over 100.

$\frac{40}{100}x=32$

Simplify the fraction.

$\frac{2}{5}x=32$

Multiply both sides by 5

$2x=160$

Divide both sides by 2

$x=80$

There were 80 lemons on the tree before he picked the lemons.

x = 88/4 = 22
The height of the kiwi is 22 inches.
