1.(3/5-7/10+1/4)(2/3-1/2-1/5)(1/4-2/3+1/8) Sacas comun denominador
(24/40 - 28/40 + 10/40)( 20/30 - 15/30 - 6/30) ( 6/24 - 16/24 + 3/24)
(6/40) ( - 1/30) ( - 7/24) multiplicamos
42 / 28800 simplificamos
7/4800
2.(1+3/5)(3/8-5/6)(3/4-5/16)+(1+3/4)
( 5/5 + 3/5)(18/48 – 40/48)(12/16 – 5/16)+ (4/4 + ¾)
(8/5)(- 22/48)(7/16) + (7/4)
( - 1232/3840) + (7/4)
( -77/240) + (7/4)
- 77/240 + 420/240
343/240
3.(2-1/5)(1/2-3/8)(-7-7/2)(3/4-1/3)
(10/5 -1/5)(4/8 - 3/8)(-14/2-7/2)( 9/12 - 4/12)
(9/5)( 1/8) ( - 21/2) ( 5/12)
- 945 / 960
- 63/64
Espero que te sirva, salu2!!!!
