Effectuer les calculs suivants :
2/5 : 9/11 = 2/5 x 11/9 = (2 x 11)/(5 x 9) = 22/45
3/7 : 8/13 = 3/7 x 13/8 = (3 x 13)/(7 x 8) = 39/56
5/8 : 9/17 = 5/8 x 17/9 = (5 x 17)/(8 x 9) = 85/72
3/2 : 7/5 = 3/2 x 5/7 = (3 x 5)/(2 x 7) = 15/14
3 : 2/7 = 3 x 7/2 = 21/2
15/4 : 7 = 15/4 x 1/7 = 15/28
2/ 5 : 9 / 11 = 2 / 5 X 11 / 9 = 22 / 45
3/7 : 8 / 13 = 3 / 7 X 8 / 13 = 24 / 91
5/8 : 9/17 = 5 /8 X 17 / 9 = 85 / 72
3/2 : 7 /5 = 3 /2 X 5 / 7 = 15 / 14
3 : 2 / 7 = 3 X 7 / 2 = 21 / 2
15 / 4 : 7 = 15 / 4 X 1 / 7 = 15 / 28
