答
1.25×68.275＋125×3.7826+1250×0.053465=1.25×68.275＋1.25×100×3.7826+1.25×1000×0.053465=1.25×(68.275＋100×3.7826+1000×0.053465)=1.25×(68.275＋378.26＋53.465)=1.25×500=625
答
原式＝1.25×68.275＋1.25×378.26＋1.25×53.465
＝1.25×﹙68.275＋378.26＋53.465﹚
＝1.25×500
＝125×5
＝625
答
1.25×68.275＋125×3.7826+1250×0.053465
=125×（0.68275+3.7826+0.53465）
=125×5
=625
答
1.25×68.275＋125×3.7826+1250×0.053465
=1.25×68.275+1.25×378.26+1.25×53.465)
=1.25×(68.275+53.465+378.26)
=1.25×500
=625
