Question

Yoko makes fruit salad using a ratio of 3 blueberries to 12 strawberries. Give two different unit rates using this relationship.
answer for one unit rate and the number___ for each _______

second another unit rate add the number____ for each__________

Answer 1

make both a fraction

Answer 2

To find the unit rates from the ratio of 3 blueberries to 12 strawberries, we can convert this ratio into unit rates.

1. **First Unit Rate**:
- The ratio of blueberries to strawberries is 3:12.
- To find the unit rate for blueberries, we divide the number of blueberries by the number of strawberries.
- **Unit rate for blueberries**: 3 blueberries for every 12 strawberries means **0.25 blueberries for each strawberry**.

So, the answer for the first unit rate is:
- number **0.25** for each **strawberry**.

2. **Second Unit Rate**:
- Similarly, we can find the unit rate for strawberries.
- **Unit rate for strawberries**: 12 strawberries for every 3 blueberries means **4 strawberries for each blueberry**.

So, the answer for the second unit rate is:
- number **4** for each **blueberry**.

In summary:
- First unit rate: number **0.25** for each **strawberry**.
- Second unit rate: number **4** for each **blueberry**.

Answer 3

To express the unit rates as fractions based on the ratio of blueberries to strawberries (3 blueberries to 12 strawberries), we can write them as follows:

1. **First Unit Rate (Blueberries per Strawberry)**:
- The ratio of blueberries to strawberries is \( \frac{3 \text{ blueberries}}{12 \text{ strawberries}} \).
- To find the unit rate for blueberries per each strawberry, we simplify it:
\[
\frac{3}{12} = \frac{1}{4}
\]
So, the first unit rate is \( \frac{1}{4} \) blueberries for each strawberry.

2. **Second Unit Rate (Strawberries per Blueberry)**:
- The ratio of strawberries to blueberries can be expressed as \( \frac{12 \text{ strawberries}}{3 \text{ blueberries}} \).
- Simplifying this gives:
\[
\frac{12}{3} = 4
\]
As a fraction: \( \frac{4}{1} \).
So, the second unit rate is \( \frac{4}{1} \) strawberries for each blueberry.

In summary:
- First unit rate: \( \frac{1}{4} \) blueberries for each strawberry.
- Second unit rate: \( \frac{4}{1} \) strawberries for each blueberry.
