0.125*(18+14)*2.5 简算

0.125*(18+14)*2.5 简算
0.125*(18+14)*2.5
=0.125*32*2.5
=0.125*8*(4*2.5)
=1*10
=10

原式=0.125*32*2.5
=(0.125*8)(2.5*4)
=1*10=10

0.125*(18+14)*2.5
=0.125*32*2.5
=0.125×8×(4×2.5)
=1×10
=10

0.125×(18+14)×2.5
=0.125×[2×9+2×7]×2.5
=0.125×[2×(9+7)]×2.5
=0.125×[2×16]×2.5
=0.125×[2×2×8]×2.5
=0.125×[4×8]×2.5
=(0.125×8)×(4×2.5)
=1×10
=10

0.125*(18+14)*2.5=(1/8)*(18+14)*(10/4)=(10/32)*32=10

0.125x8x4x2.5=10
