Answer:
a = 9
Step-by-step explanation:
you can simplify the proportion to:
use cross- multiplication
8a = 72
a = 9
3.11111... = 3 + 1/9 = 28/9
Every time you see such a repeating decimal, it's basically a fraction with 9's in the denominator.
For example:
0.222... = 2/9
0.45454545... = 45/99
0.274274274... = 274/999
