Your answer is b. hope this helps :)
Answer: we are simply to subtract the length of the gold ribbon which is 2 4/6 ft from the length of the silver ribbon, 5 2/6 feet. Mathematically,
5 2/6 feet - 2 4/6 feet = 8/3 feet
Therefore, Gina has 8/3 feet more of the silver ribbon than the golden ribbon.
It would have to be number 2 if it's a dotted line, all the other options are incorrect unless you made a mistake with one or two of the symbols.
