1c) 17/10 + 33/30
M.10={0,10,20,30...}
M. 30 ={0,30...}
c.m.m.m.c-30
17/10×3 = 51/30
33/30×1= 33/30
51+33 84
-------- = --- (poti sa simplifici daca doresti)
30 30
2a) 5/6+1-5/12
1-5/12 = 1×12+5 = 17/5
--------
5
M.6={0,6,12,18,24,30...}
M.5={0,5,10,15,20,25,30..}
c.m.m.m.c -30
5/6 × 5 = 25/30
17/5 × 6 = 102/30
25/30 + 102/30 = 127/30 (poti simplifica daca vr}
De aici cred ca te poti descurca de unul singur
succes!
