- ( 3 / 5 ) + ( 4 / 10 ) - ( - 2 / 4 ) = ???
Quitamos los parentesis :
= - 3 / 5 + 4 / 10 + 2 / 4
Simplificamos :
= - 3 / 5 + 2 / 5 + 1 / 2
- 3 / 5 + 2 / 5 = - 1 / 5
= -1 / 5 + 1 / 2
= - 2 + 5 / 10
= 3 / 10
( 4 / 5 ) - ( 6 / 8 ) + ( - 1 / 2 ) = ???
Quitamos los parentesis :
= 4 / 5 - 6 / 8 - 1 / 2
Simplificamos
= 4 / 5 - 3 / 4 - 1 / 2
= 16 - 15 - 10 / 20
= - 9 / 20
[tex] - \frac{9}{20} [/tex]
- ( 7 / 4 ) - ( 3 / 4 ) - ( + 6 / 8 ) = ???
Es - 13 / 4
