Question

Scrieti doua fractii ordinare cuprinse intre 1 supra 6 si 1supra 7

Answer 1

$\frac{1}{6};\frac{3}{20}; \frac{31}{20} ;\frac{1}{7} \\ \\ \frac{1}{6} =0,16(6) \\ \\ \frac{3}{20} =0,15 \\ \\ \frac{31}{20} =1,55 \\ \\ \frac{1}{7} =0,14$

Answer 2

1/6=0,1(6)=0,166666...≈0,166 (cu aproximatie de 1/1000 prin lipsa)
1/7=0,(142857)=0,142857...≈0,142 (cu aproximatie de 1/1000 prin lipsa)
Observam ca 0,166>0,160>0,150>0,142 ⇒ 1/6>0,166>0,16>0,15>1/7>0,142 ⇒
1/6>0,16>0,15>1/7 . Deoarece 0,16=16/100=4/25 si 0,15=15/ 100=3/20 ⇒
1/6>4/25>3/20>1/7 ; am gasit doua fractii ordinare 4/25 si 3/20 cuprinse intre 1/6 
si 1/7
