Explicație pas cu pas:
a)
³⁾1/11-1/33
= 3/33- 1/33
= 2/33
-
Proba :
2/33+1/33= 3/33
-
b)
⁸⁾7/11-⁷⁾5/8
=56/56- 35/56...........56/56= 1
= 21⁽⁷/56⁽⁷
= 3/8
-
Proba :
3/8+5/8 = 8/8 ........8/8= 1
-
d)
³⁾13/30 -²⁾2/45
= 39/90 - 4/90
= 35/90
Proba :
35/90 +²⁾2/45
= 35/90+4/90
= 39⁽³/90⁽³
= 13/30
-
d)
²⁾13/60-³⁾7/40
= 26/120 -21/120
= 5/120
-
Proba :
5/120+ ³⁾7/40
=5/120+21/120
= 26⁽²/120⁽²
= 13/60
-
d)
2⁵/₈-1³/₁₀
=⁵⁾21/8-⁴⁾13/10
= 105/ 40 -52/40
= 53/40
-
Proba :
53/40+ ⁴⁾13/10
=53/40+⁴⁾13/10
=53/40+ 52/40
= 105/40
