To find the mass of one tennis ball, we divide the total mass of the three balls by 3.
Total mass of the 3 balls = 6310 grams
Mass of one ball = Total mass / Number of balls = 6310 grams / 3
Calculating that:
\[ 6310 \div 3 = 2103.33 \text{ grams} \]
This result rounds to approximately 2103.33 grams, but since that specific value isn't in the provided responses, let's consider our options to find the closest match.
None of the responses are precisely correct since we were looking for about 2103 grams. There may have been a mistake or rounding needed. If we reconsider the available responses with standard interpretation:
- 2310 grams
- 2 Start Fraction 3 over 10 End Fraction grams
- 10189 grams
- Start Fraction 10 over 189 End Fraction grams
- 18910 grams
- 18 Start Fraction 9 over 10 End Fraction grams
- 2110 grams
The closest and most reasonable match for a mass of a single ball (assuming the errors or format issues from the response options) would be 2110 grams.
