Question

Transformati urmatoarele numere rationale in fractii ordinare ireductibile 0,25 1,2 4,(5) 0,(27) 1,4(5) 1,12(16)

Answer 1

0,25 = 25/100 ( simplificat prin 25) = 1/4
1,2 = 12/10 ( simplificat prin 2) = 6/5
4,(5) = (45-4) / 9 = 41/9
0,(27)= 27/99 (simplifcat prin 3) = 9/33 ( simplificat prin 3) = 3/11
1,4(5) = (145-14) / 90 = 131/90
1,12(16) = (11216-112) / 9900 = 11104 / 9900 ( simplifcat prin 2) = 5552/4950 ( simplificat prin 2) = 2776/2475
