Answer :
We have to rename the number 805 tens.
Since, 'tens' represents the place value of tens digit. So, the place value of 'tens' represents the value as '10'.
So, 805 tens
= [tex]805 \times 10[/tex]
= 8050
So, 805 tens is renamed as 8050.
Since, 8050 = 8050 ones
So, 805 tens = 8050 = 8050 ones.
