me ajudem e pra segunda feira pfv

Answer 1

c) 1/4 . 1/6 + 1/16

1/24 + 1/16 mmc = 384

16/384 + 24/384

40/384 = 20/192 = 10/96 = 5/48

d) 27/729 + 8/4 : 16/6

9/243 + 8/4 . 6/16

9/243 + 48/64

9/243 + 12/16

9/243 + 3/4 mmc = 972

36/972 + 729/972

765/972 simplificando: dividindo sempre por 3

255/324 = 85/108
