a) Cand imparti 2 fractii, se va folosi inmultirea iar a doua fractia se va inversa
a) 3/5 * 7/6 = 7/10
b) 7/11*33/14 = 3/2
c) 8/35*(-21/4) = -6/5
d) 84/29*(-29/35) = -12/5
e) -31/15*(-5/2) = 31/6
f) -13/100*(-50/39) = 1/6
g) 2,5=25/10=5/2
9 intregi 1/9 = (81+1)/9 = 82/9
5/2*82/9 = 205/9
h) 1,8=18/10 = 9/5
2 intregi 1/2= 5/2
9/5*5/9:5/2 = 1*2/5 = 2/5
i) 43/5*21/43:2/5 = 21/5*5/2 = 21/2
j) 308/3:154/27 = 308/3*27/154 = 18
k) 7:7/2*4/5 = 7*2/7*4/5 = 2*4/5 = 8/5
l) 77/5*15/22 = 21/2
