Bonjour;
a)
4*2/2 -3/2
= 8/2 -3/2
= 5/2
b)
2*3/3 +1/3
= 6/3 +1/3
= 7/3
c)
9/4 -1*4/4
= 9/4 -4/4
= 5/4
d)
7*4/4 +1/4
= 28/4 +1/4
= 29/4
e)
16/3 -3*3/3
= 16/3 -9/3
= 7/3
f)
4*7/7 +5/7
= 28/7 +5/7
= 33/7
g)
6*6/6 -5/3*2/2 -5/6
= 36/6 -10/6 -5/6
= 21/6
h)
2*4/4 +3/4 +7/2*2/2
= 8/4 +3/4 +14/4
=25/4
i)
7* 25/25 -9/5*5/5 -13/25
= 175/25 -45/25 -13/25
= 117/25
