Algebra I: Getting started - Ratio of monomials and polynomials

This is a free lesson from our course in Algebra I


	This lesson explains the concept of a ratio. A ratio is a way of comparing a pair of numbers or variables. Properties of ratio: � ratios can be written either using a colon to separate the quantities being compared or as a fraction. � to express any comparison as a ratio, first write the numbers as a fraction, then reduce the fraction to its lowest terms. � multiple term ratios - Three Term Ratios to be precise. Triple ratio a : b : c is read as a to b to c. You further write a : b: c :: A: B: C to say two triple ratios a : b: c and A: B: C are equal or equivalent when and only when a/b = A/B and b/c = B/C (More text below video...)

Working with polynomials

(Continued from above) Take the case of two variables a and b. You can compare these two values by showing them as a ratio a : b or as a/b. For example, the ratio of boys and girls in a class with three boys and two girls is 3 : 2. You'll also learn how it is possible to have different sets of numbers which have the same ratio, and how they can be arrived at by multiplying the ratio with a common multiple.
