Three tennis balls have the same mass if the total mass of the 3 balls is 6 3/10 grams what is the mass of 1 ball?

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

The total mass of the three balls is 6 3/10 grams, which can also be expressed as 6.3 grams.

Dividing 6.3 grams by 3, we get the mass of one ball:

6.3 grams / 3 = 2.1 grams

Therefore, the mass of one ball is 2.1 grams.
