42/28=1,5
54/81 = 2*27/3*27=2/3
85/55 = 17·5/11·5 = 17/11 = 6 + 1·11/11 = 1 6 / 11 одна целая
360/30 = 12·30/30 = 12
210/105 = 2·105/105 = 2
600/1400 = 3·200/7·200 = 3 / 7
162/135 = 6·27/5·27 = 6/5 = 1 + 1·5/5 = 1 1 / 5
500/375 = 4·125/3·125 = 4/3 = 1 + 1·3/3 = 1 1 / 3
54/81 = 2*27/3*27=2/3
85/55 = 17·5/11·5 = 17/11 = 6 + 1·11/11 = 1 6 / 11 одна целая
360/30 = 12·30/30 = 12
210/105 = 2·105/105 = 2
600/1400 = 3·200/7·200 = 3 / 7
162/135 = 6·27/5·27 = 6/5 = 1 + 1·5/5 = 1 1 / 5
500/375 = 4·125/3·125 = 4/3 = 1 + 1·3/3 = 1 1 / 3
