(- 3/7)÷4/12
41/3÷22/5
15/11÷4/5
17/5÷4/3
1/2÷1/3
(-19/8)×(-12/7)
(12/5×7/4)÷3/2
(9/8×5/4)÷(1/4×11/3)

Answer 1

 Al realiza las operaciones  se obtiene :      

(- 3/7)÷4/12   = -9/7

41/3÷22/5  = 205/66

15/11÷4/5   = 75/44

17/5÷4/3 = 51/20

1/2÷1/3   = 3/2

(-19/8)×(-12/7)  = 133/96

(12/5×7/4)÷3/2  = 14/5

(9/8×5/4)÷(1/4×11/3)= 135/88  

       

(- 3/7)÷4/12   =  - 3*12/7*4 = - 36/28 =  -9/7

41/3÷22/5  =  41*5/3*22 = 205/66

15/11÷4/5   =  15*5/11*4 = 75/44

17/5÷4/3 = 17*3/4*5 = 51/20

1/2÷1/3   =1*3/2*1 = 3/2

(-19/8)×(-12/7)  = -19*7/8*12 = 133/96

(12/5×7/4)÷3/2  = ( 12*7/5*4 )÷3/2  =  84/20 ÷3/2 = 2*84/20*3= 168/60 = 84/30 =42/15 = 14/5

(9/8×5/4)÷(1/4×11/3)=( 45/32)÷(11/12) =45*12/32*11=540/352=270/176= 135/88
