Answer 1

Resposta:

A) 14,76

B) 7,25

C) 86,25

D) 192,78

Explicação passo-a-passo:

A) 123 = 100%

x = 12%

100x = 1476

x = 1476 ÷ 100

x = 14,76

B) 145 = 100%

x = 5%

100x = 725

x = 725 ÷ 100

x = 7,25

C) 345 = 100%

x = 25%

100x = 8625

x = 8625 ÷ 100

x = 86,25

D) 567 = 100%

x = 34%

100x = 19278

x = 19278 ÷ 100

x = 192,78
