Bonjour !

Calculer:

3/7+5/6= (3x6 + 5x7)/(7x6)= (18+35)/42= 53/42

3/5-4/15= (3x3 - 4)/15= (9-4)/15= 5/15= 1/3.

2/3+1/2×5/3= 2/3 + (1x5)/(2x3)= 2/3 + 5/6= (2x2 + 5)/6= 9/6= 3/2 .

5/6:(3/4-2/3)= (5/6)/ (3x3-2x4) (4x3))= (5/6)(1/12)= (5/6)x12= (5:6)x12:6= 5x2

                    =  10

Bonjour,

3/7+5/6

= 3/7 *6/6 +5/6 *7/7

= 18/42 +35/42

= 53/42

3/5-4/15

= 3/5*3/3 -4/15

= 9/15-4/15

= 5/15

= 1/3

2/3+1/2×5/3

= 2/3+5/6

= 2/3*2/2+5/6

= 4/6+5/6

= 9/6

= 3/2

5/6/(3/4-2/3)

= 5/6 /( 3/4*3/3 -2/3 *4/4)

= 5/6 /( 9/12 -8/12)

= 5/6 /(1/12)

= 5/6*12

= 60/6

= 10

excuse-moi pour l'erreur.
