Two fifths of the fish in grays fish tank are guppies. One fourth of the guppies are red. What fraction of the fish in grays tank are red guppies?

I think it goes like this:

1/4 of 2/5 = 2/20 or 1/10

It's asking what fraction are red guppies and it's telling us that 2/5 of the tank is made up of guppies and out of that 2/5, 1/4 of them are red. So you would have to figure out what 1/4 of 2/5 is to find out how many red guppies there are.

It would be one fourth cause he tells you the fraction of how many guppies are red
