不对!再问:我知道,我是问正确的得数和算式再答:3.8-2.56=1.24
0.25=1/41.36/0.25=1.36/(1/4)=1.36X4=5.44
24.46-1.36=23.123.1+1.54=24.6424.64-6.64=18
=1.36x9.9+1.36x0.1=1.36x(9.9+0.1)=1.36x10=13.6
1.36×9.9+1.36×0.1=1.36×10=13.6
亲,可运用乘法结合律1.36×98+2.72=1.36×98+1.36×2=1.36×(98+2)=1.36×100=136
5.84*1.36+1.36*3.16+1.36=1.36*(5.84+3.16+1)=1.36*10=13.6(15*5/9)/5=(15/5)*(5/9÷5)=3*1/9=1/3
14.28-(10-2.72)=14.28-10+2.72=14.28+2.72-10=17-10=7再问:1.12/3.5/0.02的简便方法再答:1.12/3.5/0.02=1.12/(3.5*0
2.72乘2.72乘99【此连乘不好算】=269.28×99=26658.72【估计第一个不是乘,是加,那就好算了.】
(4.38-1.36)除以1.3+0.04这个算式用文字表示的意思是:4.38与1.36的差除以1.3的商与0.04的和是多少?
1.98+2.64+1.02+1.36=(1.98+1.02)+(2.64+1.36)=3+4=7解题思路就是凑整.另学习愉快
3.25×1.36+32.5×0.064-3.25=3.25×1.36+3.25×0.64-3.25=3.25*(1.36+0.64-1)=3.25*1=3.25
1.因数好像只有整数才能被称为因数,所以36.96只有1个因数就是1.2.4和9的倍数有:36,723.8和12最大公因数:4;24和36最大公因数:12;10和60最大公因数:10;5和7最大公因数
1.36*(4*2.5)=1.36*10=13.6
2.72+0.28*1.5=2.72+0.28+0.28*0.5=3+0.14=3.14
=(5.36+4.64)-(4.28+2.72)=10-7=3
5.84*1.36+13.6*0.316+1.36=5.84*1.36+1.36*3.16+1.36=1.36*(5.84+3.14+1)=1.36*10=13.6
1、0.64*7.2+3.6*2.72=0.64*2*3.6+3.6*2.72=3.6*(1.28+2.72)=3.6*4=14.42、0.78*0.45*0.1/7.8/0.045=7.8*0.04
