Answer:
D
Step-by-step explanation:
the percentage of red balls is calculated as
( number of red balls ) ÷ (total number of balls ) × 100%
total number of balls = 20 + 40 + 15 = 75
number of red balls = 20
Then
percentage red = 20 ÷ 75 × 100%
= [tex]\frac{20}{75}[/tex] × 100%
= [tex]\frac{20(100)}{75}[/tex] %
= [tex]\frac{2000}{75}[/tex]
= 26 [tex]\frac{2}{3}[/tex] %
