Question 1

Question 1:
To determine which statements are correct, we need to analyze the information given. It states that 10% of the students are 160, which means:

• Let \( x \) be the total number of students:
  \( 0.10x = 160 \)
  \( x = \frac{160}{0.10} = 1600 \)

From this, we can conclude:

1. There are 1,600 students in the school. (Correct)
2. The total number of students is > 160. (Correct)
3. The percent as a part-to-whole ratio is 10/100. (Correct)

Incorrect Statements:

• There are 250 students in the school. (Incorrect)
• The total number of students is < 160. (Incorrect)
• The percent as a part-to-whole ratio is 160/100. (Incorrect)

Correct Responses:

1. There are 1,600 students in the school.
2. The total number of students is > 160.
3. The percent as a part-to-whole ratio is 10/100.

Question 2:
To determine who solved the problem correctly, we use the formula: If 150 is 25% of a number \( x \), then: \[ 150 = 0.25x \]
\[ x = \frac{150}{0.25} = 600 \]

Thus, 150 is 25% of 600.

Without the explicit calculations from each student, I would recommend checking each student's work to see who correctly derived that 600 is the number that 150 is 25% of.

Choose the student whose work is correct based on their calculations.

Question 3:
If 5 crackers represent 5% of the entire box, we can use the formula:

• Let \( x \) be the total number of crackers in the box: \[ 0.05x = 5 \]
  \[ x = \frac{5}{0.05} = 100 \]

Thus, there were 100 crackers in the box.

Answer:
100
