Question

(1/5)+(-3/4)+(-2/12)

Answer 1

x = 1/5 + (-3/4) + (-2/12) 

x = 1/5 -3/4 - 1/6
x = (12 - 45 - 10)/60
x = -43/60

Answer 2

$(\frac{1}{5}) + (\frac{-3}{4}) + (\frac{-2}{12})$

$\frac{1}{5} + \frac{-3}{4} + \frac{-2}{12}$

$\frac{12-45-10}{60}$

$\frac{-43}{60}$

$- \frac{43}{60}$

Espero que te sirva. :D
