Question

快快快，求简便运算！！！

Answer 1

原式=1.5×(100+5)
=1.5×100 + 1.5×5
=150+7.5=157.5
原式=6×0.36 + 6×0.1×26.4
=6×0.36 + 6×2.64
=6×(0.36+2.64)
=6×3=18
原式=0.5×12.5×8×2×4×0.25
=(0.5×2)×(12.5×8)×(4×0.25)
=1×100×1=100
原式=0.75×(100 -1)
=0.75×100 - 0.75×1
=75 - 0.75=74.25

Answer 2

Answer 3

1.5*105
=1.5*（100+5）
=150＋7.5
=157.5
6*0.36+0.6*26.4
=6*0.36+6*2.64
=6*（0.36+2.64）
=6*3
=18
0.5*1.25*64*0.25
=0.5*1.25*8*4*2*0.25
=1*10*1
=10
0.75*99
=0.75*（100-1）
=75-0.75
=74.25

Answer 4

1.5X105=157.5,
6X0.36+0.6X26.4=2.16+15.84=18，
0.5X12.5X64X0.25=6.25X64X0.25=400X0.25=100，
0.75X99=74.25
