把10分之1,4分之3,0.09,1.5,8分之9,2.4,3分之7按...

把10分之1,4分之3,0.09,1.5,8分之9,2.4,3分之7按从小到大的顺序排列 化为小数: 10分之1=0.1 4分之3=0.75 0.09 1.5 8分之9=1.125 2.4 3分之7=2.333.... 所以 0.09

8.6+2.4=11 0.35÷0.7=0.5 0.5×0.2=0.1 1.25×8=10 0.36×100=36 1-0.09-0.9=0.01 2.8+3.2=6 0÷8×0.25=0 12.3-2.3=10

0.56 =14/25 0.99=99/100 0.4 =2/5 0.6 =3/5 0.8 =4/5 0.25=1/4 0.5=1/2 0.75 =3/4 0.125=1/8 0.375 =3/8 0.625 =5/8 0.875=7/8 比如:7/8表示八分之七

40/57 1/700 40/79 100/1 3/40 8/5 3/2 2/1 2/1

是好几个小数,还是?

3/4:7/8 =3/4x8/7 =6:7 1:3/5 =1x5/3 =5:3 0.24:2 =0.24÷2 =0.12 =12:100 =3:25 0.3:0.09 =30:9 =10:3 5:1/5 =5x5 =25:1 0.25:1 =0.25 =1:4

0.63×2=1.26, 4.8÷0.6=8, 1.7+3=4.7, 4×9×0.25=9, 1.25×1000=1250, 6.3÷0.1=63, 6.3+0.7=7, 2-0.09=1.91, 8.5-0.24-0.76=7.5, 0.197×51×0=0.

3.2÷4=0.8 8.4÷1.4=6 6.9÷0.3=23 8.1÷0.09=90 4.9÷7=0.7 7.2÷1.8=4 1.1÷0.5=2.2 11.1÷3.7=3 2.4÷6=0.4 7.8÷1.3=6 9.6÷3.2=3 0.96÷1.2=0.8 4.8÷8=0.6 6.8÷1.7=4 9.9÷1.1=9 0.68÷0.4=1.7

0.18=100分之18 0.43=100分之43 0.09=100分之9 7.1=10分之71 3.2=10分之32 0.625=1000分之625 1.8=10分之18 8.21=100分之821

(1)0.3+0.8=1.1 (2)0.5+1+0=1.5
