¹³/₁₂
<h3>
Further explanation</h3>
<u>Given:</u>

- A fraction represents part of a whole. 
- A fraction consists of a numerator and a denominator. i.e.,  . .
- The numerator = the number of equal parts of a whole.
- The denominator = the total number of parts that make up said whole.
From the problems above, the denominator or the bottom numbers are still different. We use the Least Common Multiple (or LCM) to equalize the denominator.
- Multiples of 3:  
- Multiples of 4:  
- Multiples of 6:  
Hence, the LCM for 3, 4, and 6 is 12.
We change the denominator for each fraction to 12.



Then we continue adding fractions.


Thus, the result is

The amount of profit the spirit club make on each shirt sold at the end of the year is = $2
<h3>Calculation of profit</h3>
The quantity of shirt bought by the club = $8 per shirt
At the end of the year they sold the shirts at discount of %25 each.
That is 25/100 × 8 
 = 200/100
 = $2
Therefore, they made profit of $2 for each shirt they sold at the end of the year.

Answer:
The length of the fence is 38 yards 
These are the expressions 
1. Perimeter = 2l+ 2w
2. Perimeter = 2(l+w)
Step-by-step explanation:
This problem bothers on the mensuration of flat shapes, a rectangle. 
The length of the fence is the perimeter of the garden which is the expression that Chole could use 
1. Perimeter = 2l+ 2w
2. Perimeter = 2(l+w)
Given data 
Length = 11 yards 
Width = 8 yards 
Perimeter = 2(11)+ 2(8)
Perimeter = 22+16
Perimeter = 38 yards

Answer: Perpendicular</h3>
=========================================================
Work Shown:
Solve the first equation for y
3x+7y = 15
7y = -3x+15
y = (-3x+15)/7
y = (-3/7)x + 15/7
The slope here is -3/7
-------
Solve the second equation for y
7x-3y = 6
-3y = -7x+6
y = (-7x+6)/(-3)
y = (7/3)x - 2
The slope here is 7/3
-------
The slopes -3/7 and 7/3 are not equal, so we don't have parallel lines.
The lines however are perpendicular because the slopes multiply to -1
(-3/7)(7/3) = (-3*7)/(7*3) = -21/21 = -1
