Jawab:
Nomor 4:
[tex]644 \div (2 \times 14) + (120 - 58) \\ = 644 \div 28 + 62 \\ = 23 + 62 \\ = 85[/tex]
Nomor 5:
[tex]a \times (16 \times 7) = (11 \times 16) \times b \\ a \times 112 = 176 \times b \\ 112a = 176b \\ \\ a + b = a + b \\ a \: dan \: b \: tidak \: ditemukan [/tex]
Nomor 6:
[tex]( - 18 - ( - 4)) \times ( - 42) \div 6 \\ = ( - 18 + 4) \times ( - 7) \\ = - 14 \times ( - 7) \\ = 98[/tex]
Nomor 7:
[tex]a = - 8 + (3 \times 4) - ( - 6 \div 3) \\ = - 8 + 12 - ( - 2) \\ = - 8 + 12 + 2 \\ a = 6 \\ \\ b = 12 + 18 \div ( - 3 \times 2) \\ = 12 + 18 \div ( - 6) \\ = 12 + ( - 3) \\ b = 9 \\ \\ a \div b \\ < = > 6 \div 9 \\ < = > (6 \div 3) \div (9 \div 3) \\ < = > 2 \div 3 \\ \\ jawaban > > 2 \div 3[/tex]
