hitunglah penjumlahan pecahan berikut ini (-3/4) + 1/3 + 5/6 = (-2/3) + (1/2 + 3/4) = 5/3 + (1/6 + 1/2) = (2/7 + 1/2 + (-3/4))= tolong dijawab yaaaa plis buat b

(-3/4) + 1/3 + 5/6
= 9+4+10/12
= 5/12

(-2/3) + (1/2 + 3/4)
= -2/3 + 5/4
= 7/12

5/3 + (1/6 + 1/2)
= 5/3 + 2/3
= 7/3

(2/7 + 1/2 + (-3/4))
= 2/7 + 1/2 - 3/4
= 1/28

maaf klau salah jawabannya
