二年级数学乘除练习题

1.口算.

5×7 = 9÷3 = 6÷3= 6×6 = 9+35 =

3×4 = 5×6 = 8×6 = 48-3 =78+9 =

37+6 = 72÷8 = 63÷7 = 18÷3 =2×35 =

6+40= 5+48 = 12×3 = 36÷9 =8+48 =

2.填空

(1)9的.3倍是( )，9是3的()倍.

(2)两个因数都是8，积是();被除数和除数同样多，商是().

(3)按要求写算式.8、9、72

( )×( )=( )( )÷( )=( )

( )×( )=( )( )÷( )=( )

　3.直接写出得数.

3×4÷6=5×9+35=54÷6÷3=72÷(23-15)=4×8-16=6×6÷4=
