$16$

Write down in math exactly what is said in English..

$20% xx 80$

$20/100 xx 80$

Simplify by cancelling the zeros (actually $div10$ each time)

: $(2cancel0)/(1cancel0cancel0) xx (8cancel0)/1$

= $16$

You can also simplify $20%$ into a fraction in its simplest form:

$cancel20/cancel100^5 xx80/1$

$80/5 = 16$
