475➗25怎么简便运算 475÷25 =(475÷25)÷(25÷25) =19÷1 =19

16800➗8➗25简便运算 16800➗8➗25 =16800÷(8*25) =16800÷200 =84

600➗4➗25的简便计算 600➗4➗25 =600÷(4*25) =600÷100 =6

600➗15+600➗5用简便方法计算 600➗15+600➗5 =40+120 =160 直接计算

908➗32➖108➗32 =(908-108)➗32 =800/32 =800/8/4 =100/4 =25

12.6x7.6x2.32➗1.9➗1.4➗2.9如何用简便计算? 12.6x7.6x2.32➗1.9➗1.4➗2.9 =(12.6÷4)*(7.6÷1.9)*(2.32÷2.9) =3.15*4*0.8 =10.08

解:9000000➗25➗125➗8➗5➗4➗2 =9000000➗(25x125x8x5x4x2) =9000000➗(25x4x5x2x125x8) =9000000➗(100x10x1000) =9

结合律。 列式为: 2100➗42 =2100➗(7x6) =2100➗7➗6 =300➗6 =50

(980-184-16)➗35 =[980-(184+16)]➗35 =[980-200]➗35 =780➗35 =(770+10)➗35 =770➗35+10➗35 =22+2/7 =22又2/7

计算: (812-56x12)➗28 =【812-(50+6)x12】➗28 =(812-600-72)➗28 =140➗28 =5
