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__________

3 answers

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.
make both a fraction

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.
