Answer:
The answer is C
Explanation:
1) The faster way to do that is to divide 5 by 6
[tex] \frac{5}{6} = 0.833 \\ 7 \frac{5}{6} = 7 + \frac{5}{6} [/tex]
2) Then, let's add that to the whole number 7 in that mixed number:
[tex]7 + 0.83 = 7.83[/tex]
3) So we can write, based on that;
[tex]7.8 < 7 \: \frac{5}{6 } < 7.9 \\ \\ or \: 7.80 < 7.83 < 7.90[/tex]
So, The answer is C
