Answer 1

17/12,11/15, 7/18, 19/24, 12/20, 8/30

denominador común 360;
360:12= 30
360:15= 24
360:18= 20
360:24= 15
360:20= 18
360:30= 12

17/12= (17•30)/(12•30)= 510/360;
11/15=(11•24)/(15•24)= 264/360;
7/18= (7•20)/(18•20)= 140/360;
19/24= (19•15)/(24•15)= 285/360;
12/20= (12•18)/(20•18)= 216/360;
8/30= (8•12)/(30•12)=96/360;

510> 285> 264> 216>140>96;

17/12> 19/24> 11/15> 12/20> 7/18>8/30
