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%.

To determine the theoretical probabilities, we'll analyze the different possible outcomes for each case.
Total number of cards = 40 (5 cards for each number from 2 to 9)
a) Sum is 12:
There are several combinations of cards that can result in a sum of 12:
Total favorable outcomes = 6 (since there are 6 possible combinations)
Total possible outcomes (since you're drawing two cards) = 40 * 40 = 1600
Probability (sum is 12) = (Number of favorable outcomes) / (Total possible outcomes)
Probability (sum is 12) = 6 / 1600 = 0.00375
b) Difference is less than 5:
There are several combinations of cards that can result in a difference less than 5:
Total favorable outcomes = 14
Total possible outcomes = 1600
Probability (difference is less than 5) = 14 / 1600 = 0.00875
c) Product is odd:
For the product to be odd, one or both of the numbers drawn must be odd. Since there are five odd numbers (3, 5, 7, 7, 9), and each number has five cards, the total number of favorable outcomes is 5 + 5 + 5 + 5 + 5 = 25.
Total possible outcomes = 1600
Probability (product is odd) = 25 / 1600 = 0.015625
To summarize:
