calculeaza:
a)6/8+1/4
b)3/3-12/13
c)12/6-1/7
d)4/3-11/11

Răspuns :

a) [tex] \frac{6}{8}+ \frac{1}{4} = \frac{3}{4} +\frac{1}{4}= \frac{4}{4} =1[/tex]
b) [tex]1- \frac{12}{13} = \frac{13}{13} - \frac{12}{13} = \frac{1}{13} [/tex]
c) [tex] \frac{12}{6} -\frac{1}{7} =2- \frac{1}{7} = \frac{14}{7} -\frac{1}{7} = \frac{13}{7} [/tex]
d) [tex] \frac{4}{3} - \frac{11}{11}= \frac{4}{3} -1= \frac{4}{3}- \frac{3}{3} = \frac{1}{3} [/tex]

Succes.
