Question

cuanto es 1/2-1/4???
3/6+2/3???
5/8-1/4???
7/2-5/8???​

Answer 1

$\frac{1}{2} - \frac{1}{4} = \frac{2}{4} - \frac{1}{4} = \frac{2 - 1}{4} = \frac{1}{4}$

$\frac{3}{6} + \frac{2}{3} = \frac{3}{6} + \frac{4}{6} = \frac{3 + 4}{6} = \frac{7}{6}$

$\frac{5}{8} - \frac{1}{4} = \frac{5}{8} - \frac{2}{8} = \frac{5 - 2}{8 } = \frac{3}{8}$

$\frac{7}{2} - \frac{5}{8} = \frac{28}{8} - \frac{5}{8} = \frac{28 - 5}{8} = \frac{23}{8}$
