First write the equation
3/n = 5
Multiply both sides by n
3/n * n = 5 * n
Simplify
3 = 5 * n
Divide both sides by 5
3/5 = 5 * n/5
Simplify
3/5 = n
Divide
0.6 = n
So 3/0.6 = 5
Part A : You want to arrange the larger negative numbers to the left, so the number farthest left would be -7, followed by -6, -5, -4, and then 0. Then 2 is next, followed by 3. So the answer would be : -7, -6, -5, -4, 0, 2, 3.
Part B : So on that day on January, it's saying the Minnesota's degree was -14 degrees Fahrenheit and New York was -5. And he's saying that New York is colder. This is incorrect because people often make this mistake when working with negative numbers. Think of the numbers on a number line, on the negative side, the farther you are away from zero, the colder it will be. The closer you are to zero on the negative side, the less colder it'll be. On the positive side, the farther you are away from zero, the hotter it will be. The closer you are to zero on the positive side, the more warmer, this is why he is incorrect.
Part C : It would be -61 degrees Fahrenheit, because as I mentioned earlier, the farther you are away from zero on the negative side, the colder it'll be.

Probability P(D and C) is (C) 1/2.
<h3>
What is probability?</h3>
- Probability is the branch of mathematics that deals with numerical descriptions of how probable an event is to occur or how likely it is that a claim is true.
- The probability of an event is a number between 0 and 1, with 0 indicating impossibility and 1 indicating certainty.
To find the probability P(D and C):
According to the task content;
- The total number of students in the class is; 300.
- The number of students who have a cat and a dog is 150.
On this note, the probability, P(D and C) is given as;
- P(D and C) = 150/300 = 1/2
Therefore, probability P(D and C) is (C) 1/2.

The correct question is given below:
300 students in a high school freshman class are surveyed about what kinds of pets they have. Of the 300 students, 200 have a dog, 180 have a cat, and 150 have a cat and a dog. Using this information, answer each of the following questions.
Let D be the event that a randomly selected student has a dog and C be the event that a randomly selected student has a cat.
What is P(D and C), the probability that a student in the class has a dog and a cat?
A) 2/3
B) 3/5
C) 1/2
D) 5/6
Answer:
6 quarts
Step-by-step explanation:
2 pints = 1 quart
4 cups = 1 quart
• 5 pints of orange juice
5 pints = 5/2 =>2.5 quarts
• 6 cups of grape juice
6 cups = 6/4 => 1.5 quarts
• 8 cups of apple juice
8 cups = 2 quarts
2.5 + 1.5 + 2 = 6 quarts
