Final answer:
After converting 3 1/3 cups to an improper fraction (10/3 cups) and dividing by the amount needed for one trial (2/3 cups), it is determined that the student can run 5 trials with 3 1/3 cups of baking soda.
Step-by-step explanation:
To determine how many trials can be run using 3 1/3 cups of baking soda when each trial requires 2/3 cups, first convert the mixed number to an improper fraction.
3 1/3 cups is equivalent to 10/3 cups because 3 cups times 3 is 9 and adding the remaining 1/3 cup gives 10/3 cups of baking soda.
Next, divide the total amount of baking soda by the amount needed for one trial:
- Total amount of baking soda: 10/3 cups
- Amount needed for one trial: 2/3 cups
The number of trials is calculated as follows:
(10/3) / (2/3) = 10/3 × 3/2 = 5
So, the student can run 5 trials with 3 1/3 cups of baking soda.
