bonjour

a ) 4 - 3/2 = 8/2 - 3/2 = 5/2

b) 2 - 1/3 = 6/3 - 1/3 = 5/3

c) 9/4 - 1 = 9/4 - 4/4 = 5/4

d) 7 + 1/4 = 28/4 + 1/4 = 29/4

e) 16/3 - 3 = 16/3 - 9/3 = 7/3

f) 4 + 5/7 = 28/7 + 5/7 = 33/7

g) 6 - 5/3 - 5/6 = 36/6 - 10/6 - 5/6 = 21/6 = 7/2

h) 2 + 3/4 + 7/2 = 8/4 + 3/4 + 14/4 = 25/4

i = 7 - 9/5 - 13/25 = 175/25 - 45/25 - 13/25 = 117/25
