1. 16%×x = 12
[tex] \frac{16}{100} \times x = 12[/tex]
[tex]x = 12 \div \frac{16}{100} [/tex]
[tex]x = \frac{12}{1} \times \frac{100}{16} [/tex]
[tex]x = \frac{1200}{16} = \frac{600}{8} = \frac{300}{4} = \frac{150}{2} = 7 \\ = > \frac{16}{100} \times 75 = 12 \\ \frac{1200}{100} = 12[/tex]
2. Ce procent reprezinta 45 din 75
%=?
[tex] \frac{p}{100} \times 75 = 45 \\ 75p = 4500 \\ p = \frac{4500}{75} = 60\%[/tex]
