( 1/3 + 3/4) : ( 5/4 - 7/3)
( 4/12 + 9/12) : ( 15/12 - 28/12)
13/12  : - 13/12
13/12 x - 12/13  = - 156/156 = - 1

Voila
1/3+3/4/5/4-7/3 = 1/3+3/4 : 5/4-7/3
                       = 1*4/3*4+3*3/4*3 : 5*3/4*3-7*4/3*4
                       = 4+9/12 : 15-28/12
                       = 13/12 : -13/12
                       = 13*12/12*-13
                       = 156/-156 = -1

Réécrivez ce texte en mettant « maîtresse » au pluriel et en remplaçant « nous » par « les
élèves :
La maîtresse se promène dans les travées entre les pupitres, sa voix sonne clair, elle articule chaque mot très
distinctement, parfois même elle triche un peu en accentuant exprès une liaison, pour nous aider, pour nous faire
entendre par quelle lettre tel mot termine.
Pouvez-vous m’aider svp
