0.56x7.8%0.56x5.8脱式计算

0.56X(7.8-5.8)=1.12

12.5x0.56x0.4x0.8x1250 =(12.5×0.8)×(0.4×1250)×0.56 =10×500×0.56 =5000×0.56 =280

1. 4×102-2×49 =408-2×49 =408-98 =310 2. 25×(2+4) =25×2+25×4 =50+100 =150 3. 12×5+8 =60+8 =68 4. 99×101 =99×(100+1) =99×100+99×1 =9900+99 =9999 5. 25×(78×4) =25×4×78 =100×78 =7800 6. (25+12)×4 =25×4+12×4 =100+48 =148 7. ...

69÷0.56x0.32 =69x0.32÷0.56 =69x0.4x0.8÷(0.7x0.8) =27.6÷0.7 =276/7 =39又7分之3

0.56×202 =0.56×(200+2) =0.56×200+0.56×2 =112+1.12 =113.12

408-12×24 = 408 - 288 = 120 (46+28)×60 = 74 x 60 = 4440 42×50-17 = 2100- 17 = 2083 32+105÷5 = 32 + 21 = 53 420×(327-238) = 420 x 89 = 37380 (4121+2389)÷7 = 6510 ÷7 = 930 3.416÷(0.016×35) = 3.416 ÷0.56 = 6.1 0.8×[(10...

10-0.56-0.44=10-(0.56+0.44)=10-1=9 望采纳 谢谢

0.56除以8等于多少用分数的脱式计算来解答 解: 0.56÷8 =56/100×1/8 =7/100
