Hey there!
[tex]Answer:\boxed{10}[/tex]
[tex]Explanation:[/tex]
Since Tomas's grandfather is 100 and he is 10 times older than Tomas, let's divide 100 by 10.
[tex]100/10=10[/tex]
Now let's try multiplying 10 by 10 to see if it is equal to 100.
[tex]10\times10=100[/tex]
So that means that Tomas is 10.
Hope this helps!
