Sagot :

Bonjour


Fraction simplifier :


5/4 : 6/2

= 5/4 x 2/6

= 5/4 x 2/(3 x 2)

= 5/4 x 1/3

= 5/(4 x 3)

= 5/12

8/7 : 9/3

= 8/7 x 3/9

= 8/7 x 3/(3 x 3)

= 8/7 x 1/3

= 8/(7 x 3)

= 8/21


9/2 : 3/4

= 9/2 x 4/3

= 9/3 x 4/2

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

= 3 x 2

= 6

3/7 : 5/11

= 3/7 x 11/5

= (3 x 11)/(7 x 5)

= 33/35


5/9 x 6/8

= (5 x 6)/(9 x 8)

= (5 x 2 x 3)/(3 x 3 x 2 x 4)

= (5 x 6)/(12 x 6)

= 5/12


4/6 x 8

= (4 x 8)/6

= (2 x 2 x 8)/(2 x 3)

= 16/3


3/7 x 8/2

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

= 3/7 x 4

= (3 x 4)/7

= 12/7


6 x 11/10

= (2 x 3 x 11)/(2 x 5)
= 33/5
