六年级上册数学计算题大全及答案

[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)/(1又3/8+1又1/40）

=(1-0.76)/2.4

=0.24/2.4

=0.1

[(0.2+1/3)*4.5]/(8又1/20-6.45）

=8/15*4.5/1.6

=2.4/1.6

=1.5

8.16-1.26/0.3*1.5

=8.16-4.2*1.5

=8.16-6.3

=1.86

8.4*[(1.2+3又1/3）/3.4-1/2]

=8.4*[68/16/3.4-1/2]

=8.4*[5/4-1/2]

=8.4*3/4

=6.3

5.8：x=3又1/2:7

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

19.38-4又7/8-5又1/8

=1.938-(4又7/8+5又1/8）

=19.38-10

=9.38

13又7/13-（6又3/5+3又7/13）

=13又7/13-3又7/13-6又3/5

=10-6又3/5

=3.4

1又3/4+[2又3/14-（2又3/14-1.875）]/2又1/12

=1又3/4-15/8*12/25

=1又3/4-9/10

=0.85

（9.4-8又2/5）/[（1.1+1/15）*1又7/18]

=1/[7/6*25/18]

=1÷175/108

=108/175
