2.4÷3= 5.2÷1.3= 6.6÷0.3= 6.3÷0.09= 1.8÷2= 7.2÷...

解答: 解:2.4÷3=0.8 5.2÷1.3=4 6.6÷0.3=22 6.3÷0.09=70 1.8÷2=0.9 7.2÷1.2=6 2.5÷0.5=5 1.5÷0.25=6 3.2÷4=0.8 5.6÷1.4=4 9.6÷3.2=3 0.64÷1.6=0.4

5-2.9=2.1, 0÷3.8=0, 6.3÷0.1×10=630, 6.6÷0.11=60, 7.6÷0.76=10, 0.1÷0.1÷55= 1 55 , 3.2+5.78=8.98, 9.2×0.01=0.092, 1.8-1.8÷3=1.2.

6.3÷0.09=70 你好,本题已解答,如果满意 请点右下角“采纳答案”。

3.7×0.5+6.3÷2 =3.7x0.5+6.3x0.5 =(3.7+6.3)x0.5 =10x0.5 =5

7.2+1.8=9, 0.45÷10=0.045, 0.125×8=1, 9.6÷0.96=10, 3÷0.5=6, 5-3.2=1.8, 6×0.5=3, 6.3÷0.9=7, 0.1-0.01=0.09, 16×0.125=2.

8.4÷24÷7 =0.35÷7 =0.05 12.8÷3.2×6.3 =4×6.3 =25.2 7.6+2.4÷80 =7.6+0.03 =7.63 7.65÷(9.6-7.1) =7.65÷2.5 =3.06 79.5÷0.75+0.25 =106+0.25 =106.25 (4.68-4.42)÷1.3 =0.26÷1.3 =0.2

(1)6×0.38,0.38小于1,6×0.38的积小于6,所以6×0.38<6.79,(2)0.36÷2.1,2.1大于1,0.36÷2.1的商小于1,所以0.36<0.36÷2.1,(3)1÷3=0.333…,0.333…>0.3,所以1÷3>0.3,(4)2.4×6.3=1.2×2×2.1×3=(1.2×3)×(2.1×2)=3.6×4.2,所以3...

0.4+0.06=0.46, 8.6-7=1.6, 1+0.45=1.45, 7×0.9=6.3, 0.78×0.1=0.078, 32.1×0.2=6.42 1.8-0.5=1.3, 3.2÷32=0.1, 0.36÷0.09=4, 4.3-2.3=2, 9.6÷0.3=32, 3.2+4.7=7.9, 2÷0.5=4, 0.1×0.1=0.01, 21÷0.3=70, 2.8+8=10.8.

6.3÷9=0.7 4.2÷2.1=2 8-2.6=5.4 4×1.5=6 0.32+0.8=1.12 1.7+0.25=1.95 0.84÷4=0.21 4.4÷0.2=22 5.6÷1.4=4 4+2.06=6.06 6.3÷0.09=70 8.8÷1.1=8 0.4×0.8=0.32 5.2÷13=0.4 0÷2.5=0 3.4-1.7=1.7 11.9+8.1÷9=12.8 3.6-3.6÷3.6=2.6 4.5÷5÷2=0.45 1.25...
