👉 Learn how to solve proportions. Two ratios are said to be proportional when the two ratios are equal. Thus, proportion problems are problems involving the equality of two ratios. When given a proportion problem with an unknown, we usually cross-multiply the two ratios and then solve for the unknown using the applicable operations.

Alternatively, we can multiply the two ratios by the LCM of the denominators of the two ratios. This eliminates the denominators, we then solve the resulting equation accordingly to obtain the unknown variable. 

It is very helpful to check your results by substituting them into the original equation to see if they are true. This also helps to identify the extraneous solutions. An extraneous solution is a solution which is obtained during the course of solving an equation but which does not hold true for the original equation.
