To find the mass of one ball, we divide the total mass of three balls by 3:
Total mass of three balls = 6 3/10 grams = 63/10 grams
Mass of one ball = (63/10) grams / 3 = 21/10 grams = 2.1 grams
So, the mass of one ball is 2.1 grams.
Three tennis ball have the same mass. If the total mass of three balls is 6 3/10 grams, what is the mass of 1 ball?
