Earth's Spheres & Internal Structure. In mathematics, a ratio indicates the number of times that a smaller number is contained within a larger number, while a rate expresses a ratio for two quantities measured in different units. The result might be students able to solve familiar problems, but often times many do not build the problem solving skills and conceptual understanding to work through difficult problems.
