Answer 1

$a) \: 12\% \: de \: 1521 \\ 1521 = 100\% \\ x = 12\% \\ 100 \times x = 1521 \times 12 \\ 100x = 18252 \\ x = 18252 \div 100 \\ x = 182.52 \\ \\b) 0.5\% \: de \: 110 \\ 110 = 100\% \\ x = 0.5\% \\ 100 \times x = 110 \times 0.5 \\ 100x = 55 \\ x = 55 \div 100 \\ x = 0.55$
12% de 1521 é igual à 182,52
e 0,5% de 110 é igual à 0,55
