She poured all the water from the first container into the second container, at which point the second container was full of water. What is the ratio of the volume of the first container to the volume of the second container?

Let the first jar's volume be and the second's be. It is given that. We find that. We already know that this is the ratio of the smaller to the larger volume because it is less than. An alternate solution is to plug in some maximum volume for the first container - let's sayso there was a volume of in the first container, and then the second container also has a volume ofso you get.
