Question

Praticando...
c) (2/5) + (9/4) =
b) (3/4) - (1/2) =
a) (2/3) + (5/3) =​

Answer 1

Olá!

$\frac{2}{5} + \frac{9}{4} = \frac{8}{20} + \frac{45}{20} = \frac{53}{20}$

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

$\frac{2}{3} + \frac{5}{3} = \frac{7}{3}$

$c= \frac{53}{20} ;b = \frac{1}{4} ;a = \frac{7}{3}$
