/ cas_g2_aide On souhaite calculer : #p - #q

Quel est le plus petit multiple commun de #d1 et #d2 ? {#1}

En effet ce nombre {#2} = {#3} x #d1 = {#4} x #d2

Réduisons ces écritures fractionnaires au même dénominateur :

#p - #q

= {#5} / {#6} - {#7} / {#8} (Ne taper que des nombres dans chacune des cases !)

= {#9} / {#10}

= {#11} / {#12} (Ecriture simplifiée ou éventuellement la même expression qu'au dessus)
