8.75-3.46-1.8*0.3 11/39*40 6-3/2-5/4-9/8-17/16 -33/32的简便运算

Answer 1

8.75-3.46-1.8*0.3
=8.75-3.46-0.54
=8.75-（3.46+0.54）
=8.75-4
=4.75

11/39*40
=11/39*（39+1）
=11+11/39
=11又39分之11

6-3/2-5/4-9/8-17/16 -33/32
=6-1-1/2-1-1/4-1-1/8-1-1/16-1-1/32
=1-1/2-1/4-1/8-1/16-1/32
=2/2-1/2-1/4-1/8-1/16-1/32
=1/2-1/4-1/8-1/16-1/32
=1/4-1/8-1/16-1/32
=1/8-1/16-1/32
=1/16-1/32
=1/32

Answer 2

8.75-3.46-1.8*0.3
=8.75-3.46-0.54
=8.75-4
=4.75

11/39*40
=11*(40/39)
=11*(1+1/39)
=11+11/39

6-3/2-5/4-9/8-17/16 -33/32
=6-1-1/2-1-1/4-1-1/8-1-1/16-1-1/32
=6-5-(1/2+1/4+1/8+1/16+1/32)
=1-(1-1/32)
=1/32
