To find the mass of one ball, we need to divide the total mass of the 3 balls by 3.
Total mass of the 3 balls = 6 3/10 grams
Dividing 6 3/10 by 3, we get:
6 3/10 ÷ 3 = (6 + 3/10) ÷ 3
= (60/10 + 3/10) ÷ 3
= 63/10 ÷ 3
= 63/10 × 1/3
= (63 × 1) / (10 × 3)
= 63/30
= 2 3/10
Therefore, the mass of one ball is 2 3/10 grams.
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?
2 1/10
10/189
2 3/10
18 9/10
