Question

Por favor me ajudem,preciso que tenha cálculo

Answer 1

Olá,

5) a) $\frac{\frac{1}{2} - \frac{2}{3}}{\frac{3}{4}} = \frac{\frac{3-4}{6}}{\frac{3}{4}} = \frac{-\frac{1}{6} }{\frac{3}{4}} = -\frac{1}{6} * \frac{4}{3} = -\frac{4}{18} = -\frac{2}{9}$

5) b) $\frac{\frac{3}{2}+\frac{1}{4}}{\frac{1}{3}-\frac{7}{2}} = \frac{\frac{6+1}{4}}{\frac{2-21}{6}} = \frac{\frac{7}{4}}{\frac{-19}{6}} = \frac{7}{4} * \frac{6}{-19} = -\frac{42}{76} = -\frac{21}{38}$
