人教版四年级数学下册期末《四则混合运算的计算技巧》专项精选试卷附答案

人教版四年级数学下册1.四则混合运算的计算技巧一、认真审题，填一填。

(每小题5分，共20分)1.根据157÷7＝22……3，我能想到( )×( )＋( )＝157。

2.在( )里填上合适的数。

380－( )＝128 ( )÷25＝48306÷( )＝17 36×( )＝9723.一列动车匀速行驶3小时，行了600千米，根据这一信息填写下表。

时间/小时 4 6路程/千米1000 18004.如果○÷△＝□(△、□均不为0)，那么△－○÷□＝( )。

二、仔细推敲，选一选。

(每小题3分，共9分)1.被减数、减数与差的和是136，则被减数是( )。

A.36B.272C.682.下面说法正确的是( )。

人教版四年级数学下册期末四则混合运算的计算技巧专项试卷附答案

人教版四年级数学下册方法技能分类评价1.四则混合运算的计算技巧一、认真审题，填一填。

(每空1分，共14分)1.根据157÷7＝22……3，我能想到()×()＋()＝157。

2.在()里填上合适的数。

380－()＝128()÷25＝48306÷()＝17 36×()＝9723.一列动车匀速行驶3小时，行了600千米，根据这一信息填写下表。

时间/小时 4 6路程/千米1000 18004.如果○÷△＝□(△、□均不为0)，那么△－○÷□＝()。

5.如果给算式“9×27－27”添上括号使运算结果最小，添上括号后的算式是()，和原来的结果相差()。

二、仔细推敲，选一选。

(每小题3分，共9分)1.被减数、减数与差的和是136，则被减数是()。

A.36B.272C.682.下面说法正确的是()。

A.一个数，加上0，减去0，乘0，都得原数B.除法是乘法的逆运算，减法是加法的逆运算C.因为0×5＝0，所以0÷0＝53.下面算式中括号运用恰当的是()。
