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?(1 point)

1 answer

To find the mass of one tennis ball, you need to divide the total mass by the number of balls.

Given that the total mass of the three balls is 6 3/10 grams, you first convert the mixed number into an improper fraction:

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

Now, divide this by 3:

\[ \text{Mass of one ball} = \frac{63/10}{3} = \frac{63}{10} \times \frac{1}{3} = \frac{63}{30} = \frac{21}{10} \text{ grams}. \]

Now, convert it back to a mixed number:

\(\frac{21}{10} = 2 \frac{1}{10}\) grams.

Thus, the mass of one tennis ball is \(2 \frac{1}{10}\) grams or 2.1 grams.
