Question

alguien que me ayude si no saben no respondan:)​

Answer 1

Respuesta:

-2/5 + 1/10 = -3/10 = -0.3

-3/7 + -1/14 = -1/2 = -0.5

12/13 +  1/3 = 49/39 = 1.256

-3/4 + -1/4 = -4/4 = -1

1/7 + 2/7 = 3/7 = 0.42857

-4/9 + -8/12 = -10/9 = -1.111

Explicación paso a paso:

-2/5 + 1/10 = ( (-2)(10) + (1)(5) ) / ( (5)(10) ) = ( -20 + 5 ) / 50 = -15/50 = -3/10 = -0.3
