Let the '?' be 'x'.

20\% \:  \: of \:  \: x = 100\% \:  \: of \:  \: 20

 \underline \bold{NOTE :} \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \\   \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \: 20\% =  \frac{20}{100} \:  \:  \:  \:  \:  \:  \:  \:  \:   \\  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  100\% =  \frac{100}{100}  = 1

 \frac{20}{100}  \times x =  1 \times 20 \\   \\ \frac{20x}{100}  =  20  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \\  \\ cancelling \: the \: zeroes \:   \:  \:  \:  \:  \:  \:  \:  \:  \\  \\  \frac{2x}{10}  = 20 \:  \:  \:  \:  \:  \:  \:  \:  \\  \\ 2x = 20 \times 10 \\  \\ 2x = 200 \:  \:  \:  \:  \:  \:  \\  \\ x =  \frac{200}{2}  \:  \:  \:  \\  \\ x = 100 \:  \:  \:  \:

 \large \bold{ \boxed{x = 100}}

∴ 20% of 100 = 100% of 20.
