Explications étape par étape

Bonjour

Simplifier les fractions :

A = 15/35

A = (3 x 5)/(7 x 5)

A = 3/7

B = 540/360

B = (180 x 3)/(180 x 2)

B = 3/2

C = 12 000 000 / 400 000 000

C = (4 000 000 x 3)/(4 000 000 x 100)

C = 3/100

Compléter :

13/16 = .../48

... = 48 x 13 / 16

... = (16 x 3 x 13)/16

... = 39

13/16 = /48

19/24 = .../48

... = 48 x 19 / 24

... = (2 x 24 x 19) / 24

... = 38

19/24 = /24

7/8 = .../48

... = 48 x 7 / 8

... = (6 x 8 x 7) / 8

... = 42

7/8 = /48

5/6 = .../48

... = 48 x 5 / 6

... = (6 x 8 x 5) / 6

... = 40

5/6 = /48
