甲数除以乙数，商正好是乙数的倒数，甲数是______．商是21，如果被除数缩小10倍，除数扩大10倍，那么商是______．

下面的程序随机产生10个小于100的整数，并找出其最大值、最小值和平均值，请将程序补充完整。(此程序是VB语言编写)
Private Sub Form_Click( )
Dim a(1 To 10)As Integer
Dim m_max As Integer，m_min As Integer
Dim s As Single
Randomize
For i=1 To 10
a(i)=______
Print a(i)
Next i
m_max=0：m_min=100
For i=1 To 10
If a(i)＞m_max Then
If a(i)＜m min Then m_min=a(i)
s=______
______
Print"最大值是："；m_max
Print"最小值是："；m_min
Print"平均值是："；______
End Sub
