(1.25+12.5+125)X8=1.25X8+12.5X8+125X8=10+100+1000=1110
125×0.1999+2×1.25×19.99+1250×0.01999=125×0.1999+2×1.25×19.99+1250×0.01999=1.25X19.99+2X1.25X19.99+1.
(125-1.25)*80=125*80-1.25*80=10000-100=9900
125×81=125×(80+1)=125×80+125×1=10000+125=10125
0.8*（125+12.5+1.25）=0.8x125+0.8x12.5+0.8x1.25=100+10+1=111
0.8×（12.5+1.25+125）=0.8×12.5+0.8×1.25+0.8×125=10+1+100=111
（125+0.125+1.25）*8=125*8+0.125*8+1.25*8=1000+1+10=1011
原式等于12.5×3.79+12.5×2.17+12.5×2.04=12.5×（3.79+2.17+2.04）=12.5×8=100
你好：（125+1.25+12.5）x0.8=125×0.8+1.25×0.8+12.5×0.8=100+1+10=111
1.25×38+125%×3-5÷4=1.25×(38+3-1)=1.25×40=50
7.52×125+4.45×12.5+3.5×1.25，=7.52×125+0.445+125+0.035×125，=（7.52+0.445+0.035）×125，=8×125，=1000．故答案为：
32÷125除数与被除数同时乘以8=（32*8）除以（125*8）=256除以1000=0.2563.7÷1.25除数与被除数同时乘以8=（3.7*8）除以（1.25*8）=29.6除以10=2.96
752×1.25+4.45×12.5+0.035×125，=752×1.25+44.5×1.25+3.5×1.25，=（752+44.5+3.5）×1.25，=800×1.25，=1000．
1.25*67.875+125*6.7875+1250*0.053375=1.25×﹙67.875＋678.75＋53.375﹚=1.25×800=1000
125×456÷7.89÷4.56×78.9÷1.25=125÷1.25×456÷4.56×78.9÷7.89=100×100×10=1000007.48×369369-3.69×748748=7.4
原式=(125*456*78.9)/(1.25*7.89*4.56)=(125/1.25)*(456/4.56)*(78.9/7.89)=100*100*10=100000如有疑问请先点击"选为满意答
1.25*67.875+125*6.7875+1.25*53.375=1.25*67.875+1.25*678.75+1.25*53.375=1.25*(67.875+53.375)+1.25*678
(125+1.25+0.125)×8=125*8+1.25*8+0.125*8=1000+10+1=1011
1.25×67.875+125×6.7875+1250×0.053375，=125×0.67875+125×6.7875+125×0.53375，=125×（0.67875+6.7875+0.5337
