Final answer:
Multiplying 17 teaspoons by 4.93 milliliters per teaspoon gives us 83.81 milliliters, which when rounded to the nearest tenth is 83.8 milliliters.
Step-by-step explanation:
To convert 17 teaspoons into milliliters, you can use the given approximation that 1 teaspoon is approximately 4.93 milliliters. Multiply the number of teaspoons by the conversion factor to find the volume in milliliters:
17 teaspoons × 4.93 milliliters/teaspoon = 83.81 milliliters.
However, if we round our answer to the nearest tenth, we get:
83.81 milliliters ≈ 83.8 milliliters.
