3.8×0.45+0.72×4.5-0.45简算算式步数越少越好,但每步要清楚3.8×0.45+0.72×4.5-0.45简算算式步数越少越好,但每步要清楚3.8×0.45+0.72×4.5-0.45
3.8×0.45+0.72×4.5-0.45简算算式步数越少越好,但每步要清楚
3.8×0.45+0.72×4.5-0.45简算
算式步数越少越好,但每步要清楚
3.8×0.45+0.72×4.5-0.45简算算式步数越少越好,但每步要清楚
3.8×0.45+0.72×4.5-0.45
=3.8×0.45+7.2×0.45-1×0.45
=0.45×（3.8+7.2-1）
=0.45×10
=4.5
3.8×0.45+0.72×4.5-0.45
=3.8×0.45+7.2×0.45-1×0.45
=(3.8+7.2-1)×0.45
=10×0.45
=4.5
把0.45提出来
0.45*（3.8+7.2-1）=4.5
3.8×0.45+0.72×4.5-0.45 都化成0.45
=3.8×0.45+7.2×0.45-0.45 提取0.45
=0.45×(3.8+7.2-1)
=0.45×(11-1)
=0.45×10
=4.5
祝学习进步
3.8×0.45+0.72×4.5 - 0.45
= 3.8 ×0.45 + 7.2 ×0.45 - 0.45
= （3.8 + 7.2 - 1）× 0.45
= 10 × 0.45
= 4.5
