Final answer:
The ratio of strawberries to blueberries in Jason's fruit salad is 4:5, meaning for every 4 cups of strawberries, there are 5 cups of blueberries. The fruit salad contains approximately 44% strawberries and 56% blueberries.
Step-by-step explanation:
The ratio of strawberries to blueberries in Jason's fruit salad is 4 cups to 5 cups. This means that for every 4 cups of strawberries, there are 5 cups of blueberries. If we assume that Jason's fruit salad contains a total of 9 cups of fruit (4 cups of strawberries + 5 cups of blueberries), then the fraction of strawberries in the fruit salad is 4/9 and the fraction of blueberries is 5/9.
We can also express the ratio as a fraction by dividing the number of strawberries and blueberries by their sum. Since the ratio is 4:5, the fraction of strawberries is 4/(4+5) = 4/9 and the fraction of blueberries is 5/(4+5) = 5/9. Therefore, the fruit salad contains approximately 44% strawberries and 56% blueberries.
