Answer:
[tex]3 \frac{7}{9}[/tex]
Step-by-step explanation:
We know that the first digit of 3.7, 3, will just be a 3.
However, if we have [tex].\overline{77}[/tex], we have to know what gets this.
If we have a number over 9, it will be that number repeating (excluding 9 itself).
So if we have .77 repeating, it would have to be [tex]\frac{7}{9}[/tex], adding 3 to this gets us [tex]3 \frac{7}{9}[/tex].
Hope this helped!
