Answer 1

2.4 7.6×3.4怎么行闹简算？
题桥拦目钥匙不明确。如果是：
2.4*3.4+7.6*3.4
=（2.4+7.6）敏带胡*3.4
=10*3.4
=34

Answer 2

解雀陵指: 原汪乎式=10－7.6+7.6×3.4
=10－顷配7.6(1－3.4)
=10+7.6×2.4
=10+(10－2.4)×2.4
= 10+24－2.4²
=34－5.76
=28.24

Answer 3

凑一个2.4出来了，枝兄提取公因数，链销在计算
＝2.4×1+（2.4+1）×7.6
＝2.4×1+2.4×7.6+1×7.6
＝2.4×（1+7.6）+7.6
＝2.4×8.6+7.6
＝（2+0.4）×8.6+7.6
＝2×8.6+0.4×8.6+7.6
＝17.2+3.44+7.6
＝棚搭游20.64+7.6
＝28.24

Answer 4

2.4+7.6×3.4
=2.4+（7+0.6）基姿×（3+0.4）搏袭绝禅哪
=2.4+7×3+7×0.4+0.6×3+0.6×0.4
=2.4+21+2.8+1.8+0.24
=23.4+2.8+2.04
=28.24
