6年级上册计算题大全800题及答案

[3/4-7/8/(5/6+4/5)]*28 =[3/4-7/8÷49/30]*28 =[3/4-15/28]*28 =3/4*28-15/28*28 =21-15 =6

(1.25*4/5-0.76)/(13/8+11/40 =(1-0.76)/2.4 =0.24/2.4 =0.1

[(0.2+1/3)*4.5]/(81/20-6.45 =8/15*4.5/1.6 =2.4/1.6 =1.5

x+32/3=5

x*93/4=71/11 x/2/5=10 62/3-x=4.25 6.4*1.7+62/5*8.3 46/7+1.75/111/14+35/6 2.16-7x=0.06 1/2x-0.5=51/2






8.16-1.26/0.3*1.5 =8.16-4.2*1.5 =8.16-6.3 =1.86

8.4*[(1.2+31/3/3.4-1/2] =8.4*[68/16/3.4-1/2] =8.4*[5/4-1/2] =8.4*3/4 =6.3

5.8x=31/2:7 3.5x=7*5.8 x=7/3.5*5.8 x=2*5.8 x=11.6

3/10*55-4x=14.5 16.5-4x=14.5 4x=2 x=0.2

19.38-47/8-51/8 =1.938-(47/8+51/8 =19.38-10 =9.38






137/13-63/5+37/13 =137/13-37/13-63/5 =10-63/5 =3.4

13/4+[23/14-23/14-1.875]/21/12 =13/4-15/8*12/25 =13/4-9/10 =0.85

9.4-82/5/[1.1+1/15*17/18] =1/[7/6*25/18] =1÷175/108 =108/175
