一、直接写出得数。
7.5+3.08 = 3－2.99 = 3÷1.5 = 6.5－3.8 =
2.7－0.27 = 4.2÷0.06 = 0.673×0 = 1.25×8 = 3.6÷1.2= 0.72÷0.9= 4.4÷4= 0.78÷6= 1.6÷2= 4÷5= 0.75÷0.3= 0.47÷4.7= 0.42÷7 = 2÷5 = 8.4÷2.1 = 0.69÷1 = 0.9×100÷1000 = 12.4－（6.3－0.4 = 4.8÷24 =
0.01÷0.001×0.1 =
2.6÷13= 4.8÷0.4=
7.2÷0.4 = 1÷0.25=
6.3÷0.3= 8÷0.5=
3.2÷1.6= 0÷8.6=
1÷0.2 = 7÷8 =
1.26÷0.6 = 0.5÷0.2 =
2.4＋3.25）= 0.01÷0.001×0.1 =
0.5×0.1÷0.5×0.1 = 0.5×0.1÷0.5×0.1 = 0.9×100÷1000 =
42.4＋7.6 = 1.58＋2.42 = 23.5＋76.5÷0.25 =
7.8－5.6 = 1.25×4 = 34.6÷0.2×4 =
0.24÷0.3 = 7.8×0.5 = 1÷0.2－1×0.2 =
57÷5.7 = 8.1－0.05 = 0.2×0.5 =
0.12×4 = 10÷2.5 3.02×100 = 0.25×8 =
9.9÷1.1 = 3.5÷0.7 = 0.9÷0.09 = 0.56÷10 =
7.5×0.1 = 8.08÷8 = 2.6÷1.3= 101×7.5 =
12.3—0.9= 1.5+3.8= 0.4×2.5= 8×1.25=
0.25+0.2= 6.3÷0.9= 0÷1.1= 4.8÷0.24=
二、用竖式计算。（除不尽的得数保留两位小数）
3.06×6.9= 0.71 ×2.5= 0.468×7.5=
6.49×0.85= 205×24= 0.36×2.8=
15.3－7.89= 64.8+24.36=
2.07÷0.23= 9.5÷0.25= 1.7÷3=
78.23÷13= 13.208÷0.26= 15.36÷1.2= 4.48÷0.35= 0.7624÷76= 93.5÷46=
三、解方程。
4x＋x = 19.5 x－3×4 = 12 45.45÷0.45= 0.006 ÷0.25=
8.4÷0.012= 1.25÷0.25=
8.93÷3.8= 1.8÷0.25=
7.79÷9.5= 36÷64=
78.6÷11= 5.63÷7.8=
26.4－3x = 15.3 7x = 98
5x－x＋14 = 18 2x－0.5×2 = 0.
4 x＋2 x＋9 = 17.4 7 y÷3 = 8.19 54÷2＋3 a = 72
5.5 m－1.3 m = 12.6 9×3－1.7 x = 13.4 8 x－2.6 x = 37.
15.6-x=1.23 1.5x=2.25 32.8÷x=4.1
x+5.1x=18.3 0.8x-1.6=3.2 3.5x - 2.1x=0.28
四、计算，能简便的要简便。
