Final answer:
To find the total number of strawberries, the ratio of 3:2:2 indicates that each part corresponds to 6 strawberries since Chris received 12 strawberries (2 parts). Multiplying the total parts (7) by 6 strawberries per part gives us 42 strawberries in total.
Step-by-step explanation:
To calculate the total number of strawberries shared, we first need to understand the ratio. The ratio given for Alex, Bobbie, and Chris is 3:2:2, respectively. Since Chris received 12 strawberries and Chris's share is represented by 2 parts in the ratio, this means that each part in the ratio is equal to 12 divided by 2, which is 6 strawberries per part.
Given the ratio of 3:2:2, we'll have:
- Alex's share = 3 parts
- Bobbie's share = 2 parts
- Chris's share = 2 parts
Now we'll calculate the total parts:
Total parts = Alex's 3 parts + Bobbie's 2 parts + Chris's 2 parts = 7 parts.
Since each part is 6 strawberries, the total number of strawberries is calculated as:
Total strawberries = 7 parts x 6 strawberries per part = 42 strawberries.
