Răspuns:
introducem intregii in fractie si aducem fractiile la acelasi numitor comun
c)x+5intregi 5/6-2intregi 1/2=6 intregi3/4
x+(5·6+5)/6-(2·2+1)2=(6·4+3)/4
x+35/6-5/2=27/4
x=³⁾27/4+⁶⁾5/2-²⁾35/6
x=81/12+30/12-70/12
x=41/12 = 3 intregi 5/12
f)7 intregi3/16-x=2 intregi5/12
(7·16+3)/16-x=(2·12+5)/12
115/16-x=29/12
x=³⁾115/16-⁴⁾29/12
x=345/48-116/48
x=229/48 = 4 intregi 37/48
