Question

Percent's % help

Answer 1

Right now there is 100 % in the graph, so removing fallow would remove 25

Answer 2

25 % and leave you with 75 %.

So wheat, rather than being 15 / 100, would be 15 / 75

which is

1 / 5

or

20%

Answer 3

Consider the percentages as land units. For example wheat is 15 land units. Total land units = 15 + 20 + 5 + 25 + 35 = 100 land units.
If fallow is removed there are 100 - 25 = 75 land units
Percentage wheat of 75 land units is
\[\frac{15}{75}\times 100=?%\]
