[tex]a) \frac{91}{100} - x = \frac{74}{100} \\\\x = \frac{91}{100} - \frac{74}{100} \\\\x = \frac{17}{100} \\[/tex]
[tex]b) x + \frac{1}{2} = \frac{9}{2} \\\\x = \frac{9}{2} - \frac{1}{2} \\\\x = \frac{8}{2}[/tex]
[tex]c) \frac{12}{4} - x = \frac{3}{4} \\\\x = \frac{12}{4} - \frac{3}{4} \\\\x = \frac{9}{4}[/tex]
[tex]d) x + \frac{1}{8} = \frac{5}{8} \\\\x = \frac{5}{8} - \frac{1}{8} \\\\x = \frac{4}{8}[/tex]
Sper că te-am ajutat!
