Bonjour
Explications étape par étape :
10/15 = (2×5)/(3×5) = 2/3
21/49 = (3×7)/(7×7) = 3/7
42/56 = (3×14)/(4×14) = 3/4
27/81 = (3×9)/(3×3×9) = 1/3
11/121 = 11/(11×11) = 1/11

bonjour, alors
10/15 = 5*2/5*3 = 2/3
21/49 = 3*7/7*7 = 3/7
42/56 = 7*6/7*8 = 6/8 = 3/4
27/81 = 9*3/9*9 = 3/9 = 1/3
11/121 = 1*11/11*11 = 1/11
