Sagot :
7/3 x 3/5 x 5/7 = 1
33/54 + 1/18 = 594/972 + 54/972 = 648/972 = 2/3
5/12 x 15/5 + 3/4 = 15x3/12x4 = 5x3x3/3x4x4 = 15/16
En espérant t'avoir aidé.
1 = 7/3 x 3/5 = 21/15 x 5/7 = 105/105 = 105.
2 = 33/54 + 1/18 = 33/76.
3 =5/12 x 15/5 = 75/60 + 3/4 = 78/64. Je pense que sa doit être sa .......!!!!!
