Question

2 intregi si 1 supra 2 -(+5 supra 4 )- 1,(5)=​

Answer 1

Răspuns:

$= -\frac{11}{36}$

Explicație pas cu pas:

$2 \frac{1}{2} - \frac{5}{4} - \frac{15-1}{9}$

$= \frac{5}{2} - \frac{5}{4} - \frac{14}{9}$

$= \frac{5}{4} -\frac{14}{9}$

Aducem la numitor comun (36):

$= \frac{5*9 - 14*4}{36} = \frac{45 - 56}{36} = -\frac{11}{36}$
