90 cat owners were asked to write down the brand of cat food their cats liked best.

The bar chart shows information about the results.

State true or false.

1 out of 6 cats like Coolkat best.

The above statement is true.

We need to know both the total that liked Coolkat and the total number of cats.

The total cats who liked Coolkat is 15.

In the question, it is given that the survey was conducted with 90 cat owners. Therefore 15 out of 90 liked Coolkat best.

Simplifying this fraction: $\frac{15}{90}=\frac{3}{18}=\frac{1}{6}$.
