Question

計(jì)算下面各題

9.07-22.78÷3.4

12.6÷0.28÷0.9

26.4×0.65+0.35

2.35×14-8.93．

Answer 1

分析：根據(jù)小數(shù)四則混合運(yùn)算的順序，按照小數(shù)四則運(yùn)算的計(jì)算法則進(jìn)行計(jì)算．

解答：解：①9.07-22.78÷3.4，
=9.07-6.7，
=2.37．

②12.6÷0.28÷0.9，
=45÷0.9，
=50．

③26.4×0.65+0.35，
=17.16+0.35，
=17.51．

④2.35×14-8.93，
=32.9-8.93，
=23.97．

點(diǎn)評(píng)：此題考查的目的是掌握小數(shù)四則混合的順序和小數(shù)四則運(yùn)算的計(jì)算法則，并且能夠正確熟練地進(jìn)行計(jì)算．
