WORK:
\(\frac{16}{unknown}\) ÷ \(\frac{20}{100}\)
\(\frac{20}{100}\) = \(\frac{2}{10}\)
(You get \(\frac{2}{10}\) from \(\frac{20}{100}\) by dividing the numerator and denominator by 10)
\(\frac{16}{unknown}\) ÷ \(\frac{2}{10}\) = \(\frac{16}{80}\)
You get \(\frac{16}{80}\) 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
