Sederhanakan operasi pecahan bentuk aljabar berikut! A.a/3-2a/27 B.3(a+c)/2bd:27(a+c)/8bd

A.a/3-2a/27 = a×9/27-a/27=9a/27-a/27 =8a/27
B.3(a+c)/2bd:27(a+c)/8bd
= 3a+3c/2bd:27a+27c/8bd
= 3a+3c/2bd × 8bd/27a+27c
= 8bd(3a+3c) / 2bd(27a+27c)
= 24abd+24bcd / 54abd+54bcd
= 24bd(a+c) / 54bd(a+c)
= 24/54 = 4/9
