Bonjour

A= (1-1/3-1/5)+3/4

​A = [(1 x 60) / (1 x 60) - (1 x 20) / (3 x 20) - (1 x 12) / (5 x 12)] + (3  x 15) / (4 x 15)

A = (60/60 - 20/60 - 12/60) + 45/60

A = 28/60 + 45/60

A = 73/60

Bonjour

A= (1-1/3-1/5)+3/4

A = (1 x 15)/(1 x 15) - (1 x 5)/(3 x 5) - (1 x 3)/(5 x 3) + 3/4

A = 15/15 - 5/15 - 3/15 + 3/4

A = 7/15 + 3/4

A = (7 x 4)/(15 x 4) + (3 x 15)/(4 x 15)

A = 28/60 + 45/60

A = 73/60
