一、直接写出得数

5.6-3.27= 660÷33÷2= 9.6÷8= 360÷18=

25+162= 9.5÷5= 506×4 = 107 ÷7 =

125×59×0= 2.4×5= 561÷4 = 2 1 ×21=

0.9×6 = 1-0.01= 25.3+6.27= 636-198=

0.24×2 = 8÷1.6= 64-24= 3.6÷0.36 =

0.2×0.5 = 4.5÷1.5= 4.9÷3.5= 21÷21=

1.2-0.8 = 0.35÷5= 56×200= 54÷21 =

0.46÷2= 4.4÷4= 46万+16万= 43÷4 3 =

7.2 + 2.8= 9.6÷0.8= 600÷50= 0.5÷0.25 =

1.2×500= 756÷7= 494-98= 0.25×48=

0.4÷0.08= 875+12.5= 3÷0.125= 9.6÷32=

2.5×0.4= 125×0.8= 25×8= 9.6×0.6=

5.6×3= 2.82+3.18= 44÷11= 1.5+0.25=

0.31×3= 33÷10= 10.8÷1= 9.08×0+9=

0.1×0.1= 1.5+0.25= 6.08×1000= 0.5+1÷1+0.5=

2-1.75= 10.6-2.7= 1.6×0.25= 0.25×4×1.2=

2.05+0.75= 8.4÷0.4= 2.3÷0.1= 4.2×15×0=

4.5÷0.5= 7.2÷0.8= 3-0.98= 8.95÷0.895=

3.8×0.01= 6×0.25= 0.01×10= 0.1+0.1×99=

19.6-1.8= 728÷7= 2.4÷0.8= 10.8÷9= 9.6÷0.8= 0.108÷2= 7.2×0.1= 0.01×0.1=

4.95÷0.9= 9.65÷0.1= 0.325×100= 2.5×8=

0. 56÷0.7= 0.125×4= 3.28×0.1= 3.9÷0.13=

51÷17= 1.8×0.5= 0÷3.5= 35÷3.5=

二、能简算的要简算

47 × 613 +37 × 613 27.5× 3.7-7.5× 3.7 2.6× 99

710 × 101- 710 35 × 99 + 35 30.34+9.76-10.34

2.25× 4.8+77.5× 0.48 2.5× 32×1.25 4.36× 12.5× 8

1.3× 11.6-1.6× 1.3 1.25×5×8 7.6×8+2.4×8

32×125×2.5 13.2 -3.7 - 6.3 0.4×0.7×0.25

2.78×8. 8+2. 78×2.2 0.95×9+0.95 1.8×101

三、求未知数

x-7=8.2 3x=2.4 x÷3.2=2

4 X-3 × 9 = 29 5X-3× =20

4+0.7X=102

X - 0.8 X = 16+6 23 ( X - 4.5) = 7 X÷ 7=12

2(X-2.6)=8 25 X-13 X=310 x+0.6=1.7 5/17-x=1/5

5/9+x=23 6x-x=0.5 x-4/9=2/3 4x+20=3.9

17+8.3 4x=50-12 4x=36 2.3x-1.02=0.36 24 x=0.6

X-5.7=2.15 3.5×2= 4.2+x 9÷X=0. 3 X÷0.5=2.6

9 +4x =40 0.2x-0.4+0.5=3.7 9.4x-0.4x=16.2
