Explicație pas cu pas:
5 : 10/7 = 5*7/10 = 7/2
4: 2/5 = 4 * 5/2 = 10
9 : 18/5 = 9 * 5/18 = 5/2
9 : 5si 1/4 = 9 : 21/4 = 9 * 4/21 = 36/21 = 12/7
10 : 7si1/2 = 10 : 15/2 = 10 * 2/15 = 20/15 = 4/3
14 : 2si1/3 = 14 : 7/3 = 14 * 3/7 = 6
4/7 : 3si1/7 = 4/7 : 22/7 = 4/7 * 7/22 = 4/22 = 2/11
5si1/3 : 3si1/9 = 16/3 : 28/9 = 16/3 * 9/28 = 16*9/3*28 = 12/7
15/14 : 3 = 5/14
8si1/10 : 6 = 81/10 : 6 = 81/10 * 1/6 = 81/60 = 27/20
