Answer:
B) 0.78
Explanation:
Since fractions can represent division, you can divde 7 by 9, which gives you 0.7777777778. 5 or more, raise the score. 4 or less, let it rest. The third 7 is more than five, so, you would raise the second to 8. You can already eliminate answers C and D because 7/9 isnt greater than 1, and 0.078 is smaller than 7/9, equaling 39/500. Hope this helps!
