For this case we have that, by definition, two equivalent fractions are those that represent the same amount. In addition, two fractions are equivalent if the products of the numerator of one and the denominator of the other are equal, that is, cross products.

Example:

$\frac {a} {b}\ and\ \frac {c} {d}\\a * d = b * c$

So, a fraction equivalent to $\frac {1} {4}\ is\ \frac {2} {8}$

$1 * 8 = 4 * 2\\8 = 8$

To obtain $\frac {2} {8}$ we must multiply:

$\frac {1} {2} * \frac {2} {4} =\\\frac {2} {8}$

Answer:

$\frac {1} {2} * \frac {2} {4}$

Answering based of you saying two numbers multiply to get 1/4.

1/8*1/8=2/8=1/4

Answer: 1/8 and 1/8

Ber [7]

Since the order of elements doesn't matter, we use the formula for combination as follows.

$nCk= \frac{n!}{k!(n-k)!}$

So the number of ways to choose 2 elements from a set of 4 elements would be
$4C2= \frac{4!}{2!(4-2)!}=6$

Thus the answer is 6.

The x-intercepts and vertex

Veronika [31]

( - 6, 0).(2, 0 ) , vertex = ( - 2, - 16)

to find the x-intercepts set f(x) = 0

x² + 4x - 12 = 0

(x + 6)(x - 2) = 0 ( equate each factor to zero and solve for x )

x + 6 = 0 ⇒ x = - 6

x - 2 = 0 ⇒ x = 2

x- intercepts are ( - 6, 0),(2, 0)

given the quadratic in standard form : y = ax² + bx + c
