Imi trebuie rapid!! Dau coroana

Answer 1

1. a. Numaratorul fractiei este 23.
2. b. 4fractii=1/11;2/11;3/11;4/11.
3. c.4 fracti=1/6;2/6;3/6;4/6
4. d,2/3=4/6=6/8(A) {0,2,1,4,6}
5. n={8,9,10,11}
6. x/y=220/88 x/y=ireductibila x/y=220/88=20/8=10/4=5/2
7. xy= 13xy - 7 = 3 * 12 - 7 = 36 - 7 = 29
8. (a1+b7+c3)/(a2+b4+c5)=(10a+1+10b+7+10c+3)/(10a+2+10b+4+10c+5)=[10(a+b+c)+11]/[10(a+b+c)+11]= 1
