WORK:
[tex] \frac{16}{unknown} [/tex] ÷ [tex] \frac{20}{100} [/tex]
[tex] \frac{20}{100} [/tex] = [tex] \frac{2}{10} [/tex]
(You get [tex] \frac{2}{10} [/tex] from [tex] \frac{20}{100} [/tex] by dividing the numerator and denominator by 10)
[tex] \frac{16}{unknown} [/tex] ÷ [tex] \frac{2}{10} [/tex] = [tex] \frac{16}{80} [/tex]
You get [tex] \frac{16}{80} [/tex] because you multiply the numerator 2 by 8 to get 16, so you have to multiply the denominator 10 by 8 as well to get 80.
ANSWER:
16 is 20% of 80
