0.76*54+0.46*76 (巧算.对的奖100分)巧算:0.76*54+0.46*76
0.76*54+0.46*76 (巧算.对的奖100分)
巧算:0.76*54+0.46*76

0.76*54+0.46*76 (巧算.对的奖100分)巧算:0.76*54+0.46*76
原式=76/100*54+0.46*76=76*0.54+76*0.46
=76*(0.54+0.46)=76

0.76*54+0.46*76=0.54*76+0.46*76=(0.54+0.46)*76=1*76=76

0.76×54+0.46×76
=76÷100×54+0.46×76
=76×0.54+0.46×76
=76×(0.54+0.46)
=76×1
