Answer 2

Resposta:

Vamos lá!

• Simplifique as frações quando necessário.

De maneira explicativa, temos:

$\dfrac{16}{100} .680=\dfrac{16.68}{10} =\dfrac{1088}{10} =108,8\\\\\\\dfrac{4}{100} .1700=\dfrac{4.17}{1} =68\\\\\\\dfrac{3}{100} .800=\dfrac{3.8}{1} =24\\\\\\\dfrac{18}{100} .124=\dfrac{2232}{100} =\dfrac{1116}{50} =\dfrac{558}{25} =22,32$
