DAU COROANA SI PUNCTE MAXIME

Answer 1

2)

a) 1/2*3/4=3/8=0,37500
b) 8/11*7/16=7/22=0,31818
c) 23/24*3/46=1/16=0,06250
d) 2/5*3/*10/21=(2/5*3/4)*10*21=1/7=0,14286
e) 3/7*6/55*14/21=(3/7*6/55)*2/3=12/385=0,03117
f) (1)2/5*(2)3/4=((1*2/5)*2)*3/4=3/5=0,60000
g) (1)3/5*(2)5/6=((1*5/5)*2)*5/6=5/3=1,66667
h) (3)4/5*1/4*(2)1/2=(((3*4/5)*1/4)*2)*1/2=3/5=0,60000
i) (1)2/5*0,4*3/14=((1*1/2)*4/10)*3/14=((1*2/5)*2/5)*3/14=6/175=0,03429

3)

 15/26=0,57692
(2)3/5=6/6=1,20000

nr.=0,57692*1,20000=0,69231..

15/26*(2)3/5=(15/26*2)*3/5=9/13=0,69231
