Answer 2

Answer:

16 balls

Step-by-step explanation:

If 5/7 of the balls are red then the fraction of balls that are not red is;

$\frac{7}{7} - \frac{5}{7} = \frac{2}{7}$

Which means 2/7 of the balls are not red. So to get the number;

$= \frac{2}{7} * 56 \\= 2 * 8$

= 16

∴16 balls are not red
