A) (9/4 - 6 ) dividido por ( -3/2)=
B) ( -3/2 - 2) x ( -3/2 -1/2)=
C) -1/2 dividido por [2-(1+1/4)]=
D) ( 2/3 -1/6-1) x [-2-(-5+7/2)]=

Answer 1

A) (9/4 - 6 ) dividido por ( -3/2)=

(9/4-6) / (-3/2) = 0

(-15/4) / (-3/2) = 0

(-15/4) / (2/-3) = 5/2

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

(3/2 - 2) x ( 3/2 - 1/2) = 0

(-7/2) x (3 - 1/2) = 0

(-7/2) x (2/2) = -7/2

R: -7/2

C) -1/2 dividido por [2-(1+1/4)]=

(-1/2) / [2 - (5/4)]= 0

(-1/2) / [  2- 5/4] =0

-1/2 /3/4 = 0

-1 /2 x 4/3 = -1 x 2/3

R: -2/3

D) ( 2/3 -1/6-1) x [-2-(-5+7/2)]=

(4 -1 -6 /6) x [-2 - (-5 + 7/2)] = 0

(-1/2) x [ -2 + 3 /2] = 0

-1/2 x  -1/2 = 1/4

R: 1/4
