Ratio Part to Part worksheet with visual examples for teaching ratios.

To solve the problems in the image, we need to determine the ratio of a specific part to the whole (part-to-part ratio) for each scenario. Let's go through each problem step by step.

---

Problem 1: The ratio of blue to red

- Image Description: There are 5 blue circles and 3 red circles.
- Solution:
- The number of blue circles is 5.
- The number of red circles is 3.
- The ratio of blue to red is written as \( \text{blue} : \text{red} \).
- Therefore, the ratio is \( 5 : 3 \).

Answer: \( 5 : 3 \)

---

Problem 2: The ratio of yellow to green

- Image Description: There are 4 yellow squares and 2 green squares.
- Solution:
- The number of yellow squares is 4.
- The number of green squares is 2.
- The ratio of yellow to green is written as \( \text{yellow} : \text{green} \).
- Therefore, the ratio is \( 4 : 2 \).
- Simplify the ratio by dividing both numbers by their greatest common divisor (GCD), which is 2:
\[
4 \div 2 = 2, \quad 2 \div 2 = 1
\]
So, the simplified ratio is \( 2 : 1 \).

Answer: \( 2 : 1 \)

Problem 3: The ratio of triangles to circles

- Image Description: There are 3 triangles and 6 circles.
- Solution:
- The number of triangles is 3.
- The number of circles is 6.
- The ratio of triangles to circles is written as \( \text{triangles} : \text{circles} \).
- Therefore, the ratio is \( 3 : 6 \).
- Simplify the ratio by dividing both numbers by their GCD, which is 3:
\[
3 \div 3 = 1, \quad 6 \div 3 = 2
\]
So, the simplified ratio is \( 1 : 2 \).

Answer: \( 1 : 2 \)

Problem 4: The ratio of bags to flowers

- Image Description: There are 2 bags and 4 flowers.
- Solution:
- The number of bags is 2.
- The number of flowers is 4.
- The ratio of bags to flowers is written as \( \text{bags} : \text{flowers} \).
- Therefore, the ratio is \( 2 : 4 \).
- Simplify the ratio by dividing both numbers by their GCD, which is 2:
\[
2 \div 2 = 1, \quad 4 \div 2 = 2
\]
So, the simplified ratio is \( 1 : 2 \).

Answer: \( 1 : 2 \)

---

Problem 5: The ratio of apples to oranges

- Image Description: There are 6 apples and 3 oranges.
- Solution:
- The number of apples is 6.
- The number of oranges is 3.
- The ratio of apples to oranges is written as \( \text{apples} : \text{oranges} \).
- Therefore, the ratio is \( 6 : 3 \).
- Simplify the ratio by dividing both numbers by their GCD, which is 3:
\[
6 \div 3 = 2, \quad 3 \div 3 = 1
\]
So, the simplified ratio is \( 2 : 1 \).

Answer: \( 2 : 1 \)

Final Answers

1. \( 5 : 3 \)
2. \( 2 : 1 \)
3. \( 1 : 2 \)
4. \( 1 : 2 \)
5. \( 2 : 1 \)

\[
\boxed{5:3, 2:1, 1:2, 1:2, 2:1}
\]
