Here is our first example. See the equation solved step-by-step. We'll use a method called 'cross multiplying'. The method used here is called 'cross-multiplying'. You can use it only when you have just one term on each side of the equals sign. ie: ☐ = ☐, where one or both of the boxes is a fraction. Note to Teachers: Despite the above disclaimer, some students will inevitably try to use 'cross-multiplying' whenever they encounter fractions, and even if there is no equality involved! To counter this tendency, I often don't teach the method at all, using the 'clearing fractions' method for examples in this section. We'll do that for the second example.
