Answer 1

Răspuns:

aduci la acelasi numitor

(-7*6+4*4 -7*2+5)/60 = (-42+16-14+5)/60= -35/60

(-8-4+15- 7*2)/24= (-12+15-14)/24= -11/24  ( aduci la acelasi numitor)

- $\frac{1}{4}$ + $\frac{1}{2}$ - $\frac{5}{3}$ +$\frac{3}{2}$ - $\frac{1}{3}$ +$\frac{1}{4}$ = $\frac{1+3}{2}$ -$\frac{5+1}{3}$= $\frac{4}{2}$ - $\frac{6}{3}$ = 2-2= 0
