18.3*0.25+5.3/0.4-3.13*2.5 简便运算 简便运算 我急用,我会赏分的18.3*0.25+5.3/0.4-3.13*2.5求求你们
0.4*2.5=1,因此一个数除以0.4,等于这个数乘2.5
18.3*0.25+5.3/0.4-3.13*2.5
=（1.83+5.3-3.13）*2.5
=4*2.5
=10

18.3*0.25+5.3/0.4-3.13*2.5
=1.83*2.5 + 5.3*2.5 - 3.13 * 2.5
=（1.83+5.3-3.13）*2.5
=4*2.5
=10

第一步
分别算出18.3*0.25，5.3/0.4，3.13*2.5
代入，得
4.575+13.25-7.825
得
10
写出来就是
18.3*0.25+5.3/0.4-3.13*2.5
= 4.575+13.25-7.825
= 10

18.3*0.25+5.3/0.4-3.13*2.5
=18.3*0.25+53/4-31.3*0.25
=18.3*0.25+53*0.25-31.3*0.25
=（18.3+53-31.3）*0.25
=40÷4
=10

原式＝18.3×0.25＋53×0.25－31.3×0.25
＝（18.3＋53－31.3）×0.25
＝40×1/4
＝10

18.3*0.25+5.3/0.4-3.13*2.5
=1.83 * 2.5 + 5.3*2.5 - 3.13 *2.5
=(1.83+5.3-3.13)*2.5
= 4*2.5
= 10

原式=18.3*0.25+5.3*2.5-3.13*2.5
=18.3*0.25+（5.3-3.13）*2.5
=18.3*0,25+（2.17）*0.25*10
=18.3*0.25+21.7*0.25
=（18.3+21.7）*0.25
=40*0.25
=10
