Solution:
Here we are given with the number 7,889.
we have been asked to find which places contain digits where one digit is ten times the value as the other digit.
Here the number 7889 can be re-written as
[tex] 7889=7000+800+80+9 [/tex]
Here we can say [tex] \frac{800}{80}=10 [/tex]
So number 100th place is ten times the number in the 10th place.
