To calculate a ratio of a number, follow these 3 steps: Add the parts of the ratio to find the total number of parts. Find the value of each part of the ratio by dividing the number by the total number of parts calculated in step 1. Multiply each part of the original ratio by the value of each part calculated in step 2.

Take, for example, the ratio 1 5/12:7/3. As each side, or term, of the ratio is a fraction, we first need to manipulate these and identify a common denominator that will allow us to find the ratio's lowest form. We'll walk …

Many ratio problems can be solved efficiently without ever using cross-multiplication. These strategies engage students in thinking about relationships in ratios and comparing the given values in different ways. Thinking about equivalent ratios should be a problem-solving strategy that students can apply to many different types of problems.
