SOLUTION
We are to obtain the total number of red balls and it fraction.
Fron the questions, the number of colored circles are
![30](https://img.qammunity.org/2023/formulas/mathematics/high-school/z4jlemkadefa3k9gkbg7tnfnvvywsij0u4.png)
Since 1/5 of the circles are red, the the fraction of red circles is
![(1)/(5)](https://img.qammunity.org/2023/formulas/mathematics/high-school/u5y4nnciiyc0ftq4somvdfvrab3jg27j4z.png)
The number of red circles will be
![(1)/(5)*30=(30)/(5)=6](https://img.qammunity.org/2023/formulas/mathematics/college/k3q2g3stkmezoj1rx2a0z0k0v6t051ugkq.png)
Therefore
Answer: There are 6 red circles and it fraction is 1/5
