Question

realiza las siguientes operaciones

Answer 1

a) (- 2/15) + ( - 5/12) =
     - 2/15 - 5/12 = - 24/180 - 75/180 = - 99/180 = - 33/60 = 11/20

b) 4/13 - ( - 3/10) =
    4/13 + 3/10 = 40/130 + 39/130 = 79/130

c) - 7/9 - 13/18 = - 126/ 162 - 117/162 = - 243/162 = - 81/54 = - 9/6 = - 3/2

d) ( - 3/4) - ( - 15/ 32) =
    - 3/4 + 15/32 = - 96/128 + 60/128 = - 36/128 = - 18/64 = - 9 /32

e) - 4/7 + ( - 11/9) =
    - 4/7 - 11/9 = - 36/63 - 77/ 63 = - 113/63 

f) ( - 5/41) - 12/7 =
   - 5/41 - 12/7 = - 35/287 - 492/287 = - 527/ 287
