the total amount of the funds is say "x", therefore, "x" is the 100% of the whole amount.

What is percentage?
A percentage is a number or ratio expressed as a fraction of 100.
Consider the total donated fund = x
Received donation = $21.7 million
It represents 38% of the charity's donated fund
Therefore
x ×[tex]\frac{38}{100}[/tex] = 21.7 million
x ×0.38 = 21.7 million
x =[tex]\frac{21.7}{.38} =57.1[/tex] million
Hence, the total donated fund is 57.1 million
