Bonjour

effectuer les calculs suivants en détaillant les étapes et simplifie si possible

-7/50 + 2/75

= (-7 x 3)/(50 x 3) + (2 x 2)/(75 x 2)

= -21/150 + 4/150

= -17/150

1/5 + (-2/3)

= (1 x 3)/(5 x 3) - (2 x 5)/(3 x 5)

= 3/15 - 10/15

= -7/15

1/12 - 1/9

= (1 x 3)/(12 x 3) - (1 x 4)/(9 x 4)

= 3/36 - 4/36

= -1/36

4/18 + 5/27

= (4 x 3)/(18 x 3) + (5 x 2)/(27 x 2)

= 12/54 + 10/54

= 22/54

= (2 x 11)/(2 x 27)

= 11/27

-17/24 + (-5/36)

= -(17 x 3)/(24 x 3) - (5 x 2)/(36 x 2)

= -51/72 - 10/72

= -61/72

3/16 - (-1/12)

= (3 x 3)/(16 x 3) + (1 x 4)/(12 x 4)

= 9/48 + 4/48

= 13/48

Bonjour

i. - 7/50 + 2/75

= (- 7 x 3) / (50 x 3) + (2 x 2) / (75 x 2)

= - 21/150 + 4/150

= - 17/150

j. 1/5 + - 2/3

= (1 x 3) / (5 x 3) - (2 x 5) / (3 x 5)

= 3/15 - 10/15

= - 7/15

k. 1/12 - 1/9

= (1 x 3) / (12 x 3) - (1 x 4) / (9 x 4)

= 3/36 - 4/36

= - 1/36

l. 4/18 + 5/27

= (4 x 3) / (18 x 3) + (5 x 2) / (27 x 2)

= 12/54 + 10/54

= 22/54

= (2 x 11) / (2 x 27)

= 11/27

m. 17/- 24 + (- 5/36)

= (- 17 x 3) / (24 x 3) - (5 x 2) / (36 x 2)

= - 51/72 - 10/72

= - 61/72

n. 3/16 -  -1/12

= (3 x 3) / (16 x 3) + (1 x 4) / (12 x 4)

= 9/48 + 4/48

= 13/48.
