(5)200-(76+40×3)(6)69×(800-700)÷5
答案

(1)原式=218+18×5

                =218+90

                =308(2)原式=(488+160)÷12

                =54

(3)原式= 4500÷(150-120)

                = 4500÷30

                =150(4)原式= 480÷(144-120)

                = 480÷24

                =20

(5)原式=200-(76+120)

                =200-196

                = 4(6)原式=69×100÷5
