The percentage is calculated by dividing the required value by the total value and multiplying by 100.
The percentage of students who packed their lunch is 60%.
Option B is the correct answer.
The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Example:
Requiredpercentage value = a
total value = b
Percentage = a/b x 100
Example:
50% = 50 /100 = 1/2
25% = 25/100 = 1/4
20% = 20/100 = 1/5
10% = 10/100 = 1/10
We have,
Of the students in sixth grade:
The number of students who packed their lunch = 3/5
This means,
Out of 5 students, 3 packed their lunch.
We can find the percentage by multiplying 3/5 by 100.
= 3/5 x 100
= 3 x 20
= 60%
Thus,
The percentage of students who packed their lunch is 60%.
Option B is the correct answer.

The percentage of students who pack lunch is 60%.
Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.
We have of all the students in sixth grade, 3/5 pack their lunch.
Assume that the percentage of students who pack lunch is [x]%. So -
x% = 3/5 x 100 = 60%
Therefore, the percentage of students who pack lunch is 60%.

Answer:
The first option 0 to π/2 radians
Step-by-step explanation:
y=5-p-x
y=(5-p)/x
y=5-px
To solve for y in the given equation xy + p = 5, we subtract p from both sides and divide by x to isolate y.
To solve for y in the equation xy + p = 5, we want to isolate y on one side. We can do this by subtracting p from both sides of the equation:
xy + p - p = 5 - p
Simplifying:
xy = 5 - p
Next, we can divide both sides of the equation by x to solve for y:
y = (5 - p) / x
So, the solution for y in terms of x and p is y = (5 - p) / x.
