Question

ex:8 macar primele 3 sau 4 sa fie desfasurate si dau coronita

Answer 1

a) 0,1=1/10
1,2=12/10
1,(3)=(13-1)/9=12/9 simplif=4/3
ex.devine -1/10:12/10:4/3=-1/10x10/12x3/4=simplif=-1/12x3/4=simplif=-1/16=-0,0625

b)1intreg 5/9=(1x9+5)/9=14/9
0,6=6/10
ex.devine :-14/9:6/10:(-7/27)=14/9x10/6x27/7=simplif=10

c)4,25=425/100
0,03=3/100
21intreg 1/4=(21x4+1)/4=85/4
425/100:(-3/100):(-85/4)=425/100x100/3x4/85=simplificam=20/3=6,(6)

d)0,(5)=5/9
150/27:[-5/9]:300/11=150/27x(-9/5)x11/300=simplif=-3000/11=-272,(72)

e)[7/6:(-14/1)]:[(-15/30):7/1]:[(-9/2):(-27/1)]=[7/6x(-1/14)]:[(-1/2)x1/7]:[(-9/2)x(-1/27)]=
(-1/12):(-1/14):1/6=-1/12x14/1x6/1=-7

f)[(-25/9):(-8/9)]:[(-1/9:11/45]:[11/3:(-7/3)]=
(25/9x9/8):(-1/9x45/11):[11/3x(-3/7)]=
25/8x(-5/11)x(-11/7)=25/8x5/7=125/56
