Bonsoir pouvez vous m’aider sur un exercice de math

Bonjour,

A=

10/3 - 1/3

= 9/3

= 3

B=

7/4 - 9/8

= 14/8 - 9/8

= 5/8

C=

(10/12 + 7/12) *3/5

= 17/12 *3/5

= 51/60

= 17/20

D=

6/36 + 700/210

= 1/6 + 70/21

=1/6 + 10/3

=1/6 +20/6

= 21/6

= 7/2

E=

(6/15 -3/10) *15/4

= 12/30 - 9/30) *15/4

= 3/30 *15/4

= 1/10 * 15/4

= 15/40

= 3/8

F=

10/9 * 18/15

= 180/ 135

= 36/ 27

= 12/ 9

= 4/3
