5.5×7.7+35×0.55-5.5脱式计算怎么写？

Answer 1

应用乘法分配律进行简便计算。
5.5×7.7+35×0.55-5.5
=5.5×7.7+3.5×5.5-5.5
=5.5×（7.7+3.5-1）
=5.5×10.2
=5.5×（10+0.2）
5.5×10+5.5×0.2
=55+1.1
=56.1

Answer 2

5.5×7.7+35×0.55-5.5脱式计算这么写：
5.5×7.7+35×0.55-5.5=5.5×7.7+3.5×5.5-5.5
=5.5×(7.7+3.5-1)
=5.5×10.2
=56.1

Answer 3

5.5×7.7+35×0.55-5.5
=5.5×（7.7+3.5一1）
=5.5×（11.2一1）
=5.5×10.2
=5.5×10+5.5×0.2
=55+1.1
=56.1

Answer 4

解.
5.5×7.7＋35×0.55－5.5
＝5.5×7.7＋3.5×10×0.55－5.5×1
＝5.5×7.7＋3.5×5.5－5.5×1
＝5.5×（7.7＋3.5－1）
＝5.5×10.2
＝56.1

Answer 5

=77*0.55+35*0,55-10*0.55
=（77+35-10）*0.55
=102*0.55
