36×(−2/3)+16:2 2/3=.... a. −11 b. −18 c. −22 d. −24

Jawaban: b. –18 Konsep! * a × b/c = (a × b)/c * A b/c = ((A × c) + b)/c * a : b/c = a × c/b = (a × c)/b * –a + b = –(a – b), jika a > b * Dahulukan operasi perkalian atau pembagian sebelum penjumlahan atau pengurangan. Pembahasan: 36 × (–2/3) + 16 : 2 2/3 = (36 × (–2))/3 + 16 : ((2 × 3) + 2)/3 = –72/3 + 16 : (6 + 2)/3 = –72/3 + 16 : 8/3 = –72/3 + 16 × 3/8 = –72/3 + (16 × 3)/8 = –72/3 + 48/8 = –24 + 6 = –(24 – 6) = –18 Jadi, hadil dari 36 × (–2/3) + 16 : 2 2/3 = –18.
