Answer 1

Explicação passo-a-passo:

Vamos lá

100% ___________12

5%______________x

100x = 60

x = 60/100 = 0,6

100%________300

20%__________x

100x = 6000

x = 6000/100 = 60

100% _______500

3%___________x

100x = 1500

x = 1500/100 = 15

100% _______ 225

15%__________ x

100x = 3375

x = 3375/100

x = 33, 75

Answer 2

Olá,

5% de 12: 0,6.

$\frac{12}{100} = \frac{x}{5} \\ \\ 100x = 60 \\ x = 60 \div 100 \\ x = 0.6$

20% de 300: 60.

$\frac{300}{100} = \frac{x}{20} \\ \\ 100x = 6000 \\ x = 6000 \div 100 \\ x = 60$

3% de 500: 15.

$\frac{500}{100} = \frac{x}{3} \\ \\ 100x = 1500 \\ x = 1500 \div 100 \\ x = 15$

15% de 225: 33,75.

$\frac{225}{100} = \frac{x}{15} \\ \\ 100x = 3375 \\ x = 3375 \div 100 \\ x = 33.75$

Espero ter ajudado :-) Boa sorte.
