What is Ratio?
A ratio is defined as a relationship between two quantities, it is expressed as one divided by the other
What are Arithmetic operations?
Arithmetic operations can also be specified by adding, subtracting, dividing, and multiplying built-in functions.
/ Division operation: Divides left-hand operand by right-hand operand
For example 4/2 = 2
W have been given that It takes 2 1/2 poster boards to display half of your project.
Here 2 1/2 poster boards = 2.5 poster board
Let you need poster boards would be x for your entire project
We can write this as a ratio as
2.5 poster board : 0.5 of project = x : 1 project
⇒ 2.5/0.5 = x/1
⇒ x = 25/5
⇒ x = 5
Therefore, you will need 5 poster boards for the entire project.

Answer:
Preston has 19 games and Horatio has 30 games
Step-by-step explanation:
This problem is solved by a system of equations. First, the variables are defined:
p: Preston video games
h: Horatio video games
It is known that between them they have 49 video games, that is to say that between them they add 49 games. So the first equation is p+h=49.
On the other hand, it is known that Horatio has 11 video games more than Preston. This means that h=p+11
So, now you have the system of equations. To solve it, there are several methods. In this case the substitution is used, which consists on isolate a variable in one of your equations and replacing on the other equation.
In this case, you have an isolated variable: h=p+11. By replacing it in p+h=49, you get: p+p+11=49
Now you have an equation with a variable, which can be solved:
2*p+11=49
2*p=49-11
2*p=38
p=19
This means that Preston has 19 video games.
Now you have to determinate how many video games have Horatio. For that you know that h=p+11, and you knwo the value of p. Simply replacing you get the value of h
h=p+11
h=19+11
h=30
This means that Horatio has 30 video games.
h = p + 11
p + p + 11 = 49
2p = 38
Preston has 19 games
Horatio has 30

Of the 200 packages of bagels sold, 15 of them are sesame seed bagels. What percent of the bagel packages sold are sesame seed bagels?
The fraction represents the number of sesame seed bagel packages out of all the packages.
To find out what percent are sesame seed bagel packages, we can turn the fraction into a percent.
We can first reduce the fraction by dividing both the numerator and denominator by the Greatest Common Factor of 15 and 200 using 5.
15 ÷ 5 = 3
200 ÷ 5 = 40
3 ÷ 40 = 0.075
0.075 × 100 = 7.5%
Therefore, 7.5% of the bagel packages sold were sesame seed bagels.
15 = * 200
15 = 2x / ÷ 2 (both sides)
x = 7.5 [percent]
