Three tennis balls have the same mass. If the total mass of the 3 balls is 6 3/10

Question

grams, what is the mass of 1 ball?(1 point)

Answer 1

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.
