To identify equivalent fractions we must check them by performing the operation (division) or cross products, if the result is the same they are equivalent fractions.
<h3>What are equivalent fractions?</h3>
Equivalent fractions are a mathematical term to refer to those fractions that represent the same quantity even though the numerator and denominator are different.
<h3>How do we know if two fractions are equivalent?</h3>
Two fractions are equivalent if the products of the numerator of one and the denominator of the other are equal, that is, cross products.
Let's see an example:
Let us check if
and
are equivalent.
To do this, we multiply the numerator of one of the fractions by the denominator of the other, as shown below:
Since the result is the same, we can say that the fractions are equivalent.
Note: This question is incomplete because there is some information missing. However I can answer it based on my general prior knowledge.

Answer:
w=2
Step-by-step explanation:
A=length times width (A=lw)
w= l-3
A=10
Substituting in, we get:
10= l(l-3)
Now, solve the equation.
10=
-3l
-3l-10=0
(l+2) (l-5)=0 (factoring the equation)
Therefore, l= -2 or 5
Throw out the negative value because a length of rectangle will never be negative.
Now let's solve for width
Remember w=l-3
therefore
(5)-3=2
so, w=2
(honestly, this is easier to just do in your head. But here is the long form math if you happen to run into more complicated problems.)
The product is C. -20. Good luck!
Answer:

Step-by-step explanation:
The area of a rectangle can is defined as
where w is the width and l is the length. The width in this case is 12 and the length is 15. Also it doesn't really matter what order you put it in. This gives you an area of 
Answer:
x=6, x=-8
