The ratio of neon fish to all the fish in the aquarium is 3 : 4 .
In the question ,
it is given that
in Mrs. Jone's class room there are angel fish and neon fish
number of angel fish in the aquarium = 14 fish
number of neon fish in the aquarium is = 42 fish
So, the total number of fish in the aquarium = number of angel fish + number neon fish
total number of fish = 14 + 42
= 56
the ratio of neon fish to all the fish in the aquarium is
= number of neon fish : total number of fish
= 42 : 56
since the ratio is written in simplest form ,
we get
= 6 : 8
= 3 : 4
Therefore , The ratio of neon fish to all the fish in the aquarium is 3 : 4 .

<span>f(x)↦f(x)+k
k = g(x) - f(x)
k = 13x - 17 -(13x +1)
k = 13x -17 - 13x -1
k = -18</span>
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.
