Marvin and Jane are visiting the pet store. They see 15 goldfish in the aquarium. 4 of the goldfish are orange and 11 of them are silver in color. What fraction of the fish are silver?

11/15

To determine the fraction of goldfish that are silver, we need to find the ratio of the number of silver goldfish to the total number of goldfish.

Given that there are 15 goldfish in total, and out of those, 11 are silver, we can write this as a fraction:

Silver goldfish / Total goldfish

= 11 / 15

Therefore, the fraction of goldfish that are silver is 11/15.
