Bonjour,
A = 3 x 1/5
4 + 1/3
4 + 5
A = 3/5_____
4 x 3 /1 x 3 + 1/3
4 + 5
A = 3/5
4/3 + 1/3
9
A = 3/5 : 5/3 : 9
A = 3/5 x 3/5 : 9
A = 9/25 x 1/9
A = 9/225
A = 9 x 1 / 9 x 25
A = 1/25
A = 3 x 1/5
4 + 1/3
4 + 5
A = 3/5_____
4 x 3 /1 x 3 + 1/3
4 + 5
A = 3/5
4/3 + 1/3
9
A = 3/5 : 5/3 : 9
A = 3/5 x 3/5 : 9

A = 9/225
A = 9 x 1 / 9 x 25
A = 1/25
