Explications étape par étape

Bonsoir

45/14 x 49/60

= 49/14 x 45/60

= (7 x 7)/(7 x 2) x (3 x 15)/(4 x 15)

= 7/2 x 3/4

= 21/8

5/3 x 4/5

= 5/5 x 4/3

= 4/3

45/26 x 65/72

= 45/72 x 65/26

= (9 x 5)/(9 x 8) x (13 x 5)/(13 x 2)

= 5/8 x 5/2

= 25/16

2 x 9/6

= 2 x (3 x 3)/(3 x 2)

= 2 x 3/2

= 2/2 x 3

= 3

7/6 x 6/7

= 7/7 x 6/6

= 1

25 x 11/50

= 11 x 25/50

= 11 x 25/(25 x 2)

= 11/2
