Problem 2:

The ratio of students with blond hair to students with brown or black hair is 1:2. If there are 212 students with brown or black hair, how many students have blond hair?

#### Solution:
- The ratio of students with blond hair to students with brown or black hair is 1:2.
- Let the number of students with blond hair be \( x \).
- According to the ratio, for every 1 student with blond hair, there are 2 students with brown or black hair.
- We are given that there are 212 students with brown or black hair. Therefore:
$$
\frac{x}{212} = \frac{1}{2}
$$
- Solving for \( x \):
$$
x = \frac{212}{2} = 106
$$

Answer:
$$
\boxed{106}

Problem 4:

The ratio of students who made the honor roll to the total number of students is 1:50. If there are 500 students in total, how many made the honor roll?

#### Solution:
- The ratio of students who made the honor roll to the total number of students is 1:50.
- This means for every 50 students, 1 student made the honor roll.
- If there are 500 students in total, we can find the number of students who made the honor roll by dividing the total number of students by 50:
$$
\text{Number of students who made the honor roll} = \frac{500}{50} = 10
$$

Answer:
$$
\boxed{10}

Problem 5:

12 students play on the school’s basketball team and 36 students play on the football team. What is the ratio of basketball players to football players?

#### Solution:
- The number of students playing basketball is 12.
- The number of students playing football is 36.
- The ratio of basketball players to football players is:
$$
\frac{\text{Basketball players}}{\text{Football players}} = \frac{12}{36} = \frac{1}{3}
$$
- Simplifying the ratio gives 1:3.

Answer:
$$
\boxed{1:3}

Problem 6:

The ratio of students getting an "A" in math to students getting a "B" is 1:2. If 22 students received an "A", how many received a "B"?

#### Solution:
- The ratio of students getting an "A" to students getting a "B" is 1:2.
- This means for every 1 student who got an "A", 2 students got a "B".
- We are given that 22 students received an "A". Let the number of students who received a "B" be \( x \). According to the ratio:
$$
\frac{22}{x} = \frac{1}{2}
$$
- Solving for \( x \):
$$
x = 22 \times 2 = 44
$$

Answer:
$$
\boxed{44}
$$
