36×(20÷12)

(1)原式=(102-2)×25 =100×25 =2500 (2)原式=135×(100-1) =13500-135 =13365 (3)原式=960-(120+51) =960-171 =789 (4)原式=(2052-432)÷20 =1620÷20 =81

(7/12-3/20)÷(1/4+1/9) =(35/60-9/60)÷(9/36+4/36) =13/30÷13/36 =13/30×36/13 =6/5

=360÷(12×3) =360÷36 =10

每箱要花 36×20÷(20+10) =720÷30 =24(元)

(1)14760÷36-24×11,=410-264,=146;(2)5.2×4.5+4.5×3.8+4.5,=4.5×(5.2+3.8+1),=4.5×10,=45;(3)12.5×25×0.4×0.8,=(12.5×0.8)×(25×0.4),=10×10,=100;(4)5-( 6 7 ÷ 3 14 + 6 13 ),=5-(4+ 6 13 ),=5-4- 6 13 ,=1- 6...

36÷4等于912+9=21 列综合算式 12+36÷4 =12+9 =21

182÷[36÷(12+6))] =182÷[36÷18] =182÷2 =91 360-260÷20×5 =360—13×5 =360-65 =295

(1)原式=(-3-6-11)+(2+9)=-20+11=-9;(2)原式=16×(-24)?34×(-24)+112×(-24)=-4+18-2=14-2=12;(3)原式=-10-(-5)×12×(-20)=-10-50=-60;(4)原式=?1?12×13×(2-9)=-1+76=16;(5)原式=(?12)×(?12)×(?1100)=144×(?1100)=-1...

因为120和36分别是20和12的倍数,因此做的时候没有剩余。所以可以做的面数: (120÷20)×(36÷12)×2 =6×3×2 =36面
