Calculer et donner les résultats sous la forme fractionnaire la plus simple possible.

H = 4/3 + 5/2 x 7/15

H = 4/3 + 35/30

H = (4 x 2) / (3 x 2) + (5 x 7) / (5 x 6)

H = 8/6 + 7/6

H = 15/6

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

H = 5/2.

I = - 7/4 x (1/5 - 3/10)

I = - 7/4 x [(1 x 2) / (5 x 2) - 3/10]

I = - 7/4 x (2/10 - 3/10)

I = - 7/4 x (- 1/10)

I = 7/40

J = 8/3 + 5 : (1 - 2/5)

J = 8/3 + 5 : [(1 x 5) / (1 x 5) - 2/5]

J = 8/3 + 5 : (5/5 - 2/5)

J = 8/3 + 5 : 3/5

J = 8/3 + 5 x 5/3

J = 8/3 + 25/3

J = 33/3

J = (3 x 11) / (3 x 1)

J = 11

K = (1 + 1/2) / (1/4 - 3)

K = [(1 x 2) / (1 x 2) + 1/2] : [1/4 - (3 x 4) / (1 x 4)]

K = (2/2 + 1/2) : (1/4 - 12/4)

K = 3/2 : (- 11/4)

K = 3/2 x (- 4/11)

K = - 12/22

K = (2 x - 6) / (2 x 11)

K = - 6/11
