Method 1
We can find the number of Devon's movie collection by multiplying its percentage by the number of Action movies. That is;
Number of Devon's movie collection
Method 2
We can also use ratio and proportion. According to the question, out of every 100 Action movies 85 are Devon's Movie collection. This means,
Action movies Devon's collection
100 85
20
If 100 corresponds to 85, then 20 will correspond to a less value than 85. If less more divides,Hence,
.
Therefore he has 17 movies that are in Devon's collection.

In order to add or subtract fractions, they must have the
same denominator. You need to change both of these
fractions to have the same denominator ... without changing
their values, of course.
The smallest common denominator for these fractions is 20 .
3/4 is the same amount as 15/20 .
3/5 is the same amount as 12/20 .
Now that they have the same denominator, you can do
the subtraction.
3/4:-
3*5=15
4*5=20
3/5:-
3*4=12
5*4=20
Now we can subtract easily because we have common denominators.
15/20-12/20
15-12/20
3/20
Now we have our most simple answer: 3/20

3x - 4y = -2
x + 8y = -23
_________
Our goal is to essentially get rid of one of the variables. We can do so by multiplying the first equation by 2:
6x - 8y = -4
x + 8y = -23
__________
7x = -27
x = -27/7
Input x into one of the equations to solve for y:
-27/7 + 8y = -23
-27 + 56y = -161
56y = -134
y = -134/56
y = -67/28
(-27/7, -67/28)
