Plssssss! Ajutor!!!!Am nevoie pe luni asta!

Answer 1

Buna! Uite rezolvarea:

Factor comun =fc

a) fc=10
10•(7/9+20/9)=10•27/9=10•3=30

b) fc=3/2
3/2•(8/7-1/7)=3/2•7/7=3/2•1=1,5

c) fc=4/3
4/3•(10/9-2/3)=4/3•(10/9-6/9)=4/3•4/9=16/27

d) fc=7/12
7/12•(23/27+4/27)=7/12•27/27=7/12•1=7/12

e) fc=2/34
2/34•(7/15+51/5)=2/34•(7/15+153/15)=2/34•160/15=320/510

f) fc=24/35
24/35•(18/25+2/15+11/75)

g) fc= 12/49
12/49•(81/25-1/35+4/25)

Sper ca e bine, poti sa mai verifici! Succes la scoala!
