<h3>
What is a fraction?</h3>
- A fraction is a portion of a whole or, more broadly, any number of equal parts.
- In everyday English, a fraction represents the number of pieces of a specific size, such as one-half, eight-fifths, or three-quarters.
- A common, vulgar, or simple fraction that consists of a numerator above a line and a non-zero denominator below that line.
- Numerators and denominators are also employed in uncommon fractions such as compound fractions, complex fractions, and mixed numerals.
To find what fraction of the marbles now in the bag is blue:
- Important information is that immediately before the last step blue marbles formed
from the marble in the bag. - That means that there were
blue and
other marbles, for some
. - When we double the number of blue marbles, there will be
blue and
other marbles. - Hence, blue marbles now form
all marbles in the bag.
Therefore, (C)
fraction of the marbles now in the bag is blue.

Complete question:
A bag initially contains red marbles and blue marbles only, with more blue than red. Red marbles are added to the bag until only 1 / 3 of the marbles in the bag are blue. Then yellow marbles are added to the bag until only 1 / 5 of the marbles in the bag are blue. Finally, the number of blue marbles in the bag is doubled. What fraction of the marbles now in the bag are blue?
(A) 1/5
(B) 1/4
(C) 1/3
(D) 2/5
(E) 1/2

Answer:
1. C, E, G
2. A, D, H
Step-by-step explanation:
Compare each equation to the form ...
f(x) = 1/(4p)(x -h)^2 +k
In this form, p is the distance from the vertex to the focus (positive is up), and (h, k) is the location of the vertex. The focus is (h, k+p); the directrix is y=k-p.
1. The equation tells us ...
(h, k) = (1, 4)
1/(4p) = (-1) . . . ⇒ . . . p = -1/4
So, we have ...
- vertex: (1, 4) . . . . . . . . (G)
- focus: (1, 3 3/4) . . . . . (C)
- directrix: y=4 1/4 . . . . (E)

2. The equation tells us ...
(h, k) = (-1, 4)
1/(4p) = 2 . . . ⇒ . . . p = 1/8
So, we have ...
- vertex: (-1, 4) . . . . . . . . (A)
- focus: (-1, 4 1/8) . . . . . . (H)
- directrix: y = 3 7/8 . . . (D)
