Answer 1

Respuesta:

A $\frac{1}{4}+\frac{3}{4}= 1$

B $\frac{9}{16}-\frac{7}{15}=\frac{23}{240}$

C $\left(\frac{1}{4}+\frac{3}{4}\right)-\frac{2}{4}=\frac{1}{2}$

D $\left(\frac{7}{12}-\frac{2}{12}\right)-\left(\frac{4}{12}-\frac{1}{12}\right)= \frac{1}{6}$

E $\left(\frac{5}{17}+\frac{9}{17}\right)-\left(\frac{13}{17}-\frac{7}{17}\right)= \frac{8}{17}$
