Question

calcula:
a)2/3+4-1/2
b)1/2-3/5+7/10
c)1/8+11/16-7/4
d)4/15+1-2/5
​

Answer 1

Explicación paso a paso:

$a) \frac{2}{3} + 4 - \frac{1}{2} = \frac{4 + 24 - 3}{6} = \frac{25}{6} \\ \\ b) \frac{1}{2} - \frac{3}{5} + \frac{7}{10} = \frac{5 - 6 + 7}{10} = \frac{6}{10} \\ \\ simplificamos \: y \: queda \: \frac{3}{5} \\ \\ c) \frac{1}{8} + \frac{11}{16} - \frac{7}{4} = \frac{2 + 11 - 28}{16} = - \frac{15}{16} \\ \\ d) \frac{4}{5} + 1 - \frac{2}{5} = \frac{4 + 5 - 2}{5} = \frac{7}{5}$
