五年级计算试题

1-0.45=0.55

0.65+0.35=1

0.5-0.24=0.26

6.3+3.6=9.9

4.8-0.9=3.9

0.2-0.02=0.18

0.3-0.12=0.18

0.05+0.4=0.45

7.2-3.5=3.7

2.4+0.56=2.96

0.15+0.5=0.65

25÷100=0.25

0.56×1000=560

7×0.11=0.77

2.6÷2=1.3

4÷8=0.5

500÷10000=0.05

2.03×10=20.3

1.2×3=3.6

二、柱竖向计算。(可以查几个问题)

4.75+2.466=7.216

9.05-0.532=8.518

7.45+4.3=11.75

30-0.275=27.725

0.35×66=23.1

11.2÷7=1.6

0.016×240=3.84

0.125×4.2=0.525

3.58×0.024=0.08592

26.48÷8=3.31

49.5÷15=3.3

0.609×0.8=0.4872

第三，简单计算。

1.82+2.9+0.18+3.1

=1.82+0.18+2.9+3.1

=2+6

=8

10.45+3.758-0.45

=10.45-0.45+3.758

=10+3.758

=13.758

7.04-(2.35+1.04.)

=7.04-1.04-2.35

=6-2.35

=3.65

8.44-(3.8+1.44)

=8.44-1.44-3.8

=7-3.8

=3.2

15.39-(8.7-0.61)-0.3

=15.39-8.7+0.61-0.3

=15.39+0.61-(8.7+0.3)

=16-9

=7

18.94-(2.75+8.94)

18.94-8.94-2.75

=10-2.75

=7.25

25.6-5.72-4.28

=25.6-(5.72+4.28)

=25.6-10

=15.6

1.25×40×25

=1.25×1000

=1250

0.48×101-0.48

=0.48×(101-1)

=0.48×100

=48

0.735×62+38×0.735

=0.735×(62+38)

=0.735×100

=73.5

98×0.36

=(100-2)×36

=100×36-2×36

=3600-72

=3528

2.56×99

=2.56×(100-1)

=2.56×100-2.56

=256-2.56

=253.44

2007+4×15

=2007+60

=2067

2067÷7=295余2
