bonjour;
A=
(5*9)/( 2*3)
= 45/6
= 15/ 2
B)
3/7*2/2 +1/14
= 6/14 +1/14
= 7/14
= 1/7
C)
5/2*2/2 -3/4
= 10/4 -3/4
= 7/4
D)
(3*5)/4
= 15/4
E)
(7/9)* ( -5/2)
= -35/18
F)
(2/3)*( 7/10)
=14/30
= 7/15
G)
3- 5/3 = 9/3 -5/3 = 4/3
(4/3) * (5/8)
= 20/24
= 10/12 = 5/6
H)
1/2*2/2 +1/4
= 2/4 +1/4 = 3/4
3/5 *4/4 = 12/20
3/4*5/5 = 15/20
12/20 -15/20 = -3/20
3/4* -20/3
= -80/12 = -40/6= -20/3
