ini nomor 4) tolong di jawab pake cara ya

4/9 + 11/18 + 5/27 - 4· 2/3= 4/9 + 11/18 + 5/27 - 14/3
                                         = 4(6) + 11(3) + 5(2) - 14(18) /54
                                         =24+33+10-252 /54
                                         =-185/54
                                         = -3·23/54

4/9 + 11/18 + 5/27 - 4 2/3
= 4/9 + 11/18 + 5/27 + 12/3
Kita samakan dulu penyebutnya.

= 24 + 33 + 10 - 216 /54.
= 67/54 - 252/54 = -185/54


Maaf jika salah. Semoga membantu ^_^
