2 1/10 grams

Answer 1

To find the mass of one ball, we need to divide the total mass of the 3 balls by 3.

Given that the total mass is 6 3/10 grams, we can convert it to an improper fraction:

6 3/10 = (6 * 10 + 3)/10 = 63/10

Now, divide 63/10 by 3:

63/10 ÷ 3 = 63/10 * 1/3 = 63/30 = 21/10

Now, convert 21/10 back into a mixed number:

21/10 = (2 * 10 + 1)/10 = 2 1/10

Therefore, the mass of one ball is 2 1/10 grams.

The correct answer is 2 1/10 grams.
