Question

2. There are 15 balls in a bag and one-fifth of
balls are red and one-third of the balls are
blue and rest of them are green. Find how
many balls are red, blue and green?​

Answer 1

Step-by-step explanation:

Red balls : Blue balls

1/5 : 1/3

Taking LCM of the denominators

3/15 : 5/15

Thus, red balls is 3/15 of 15 balls = 3 red balls

blue balls is 5/15 of 15 balls = 5 blue balls

Rest are green balls

15 - (3+5)

15 - 8

7 green balls
