That was a very simple equation. Let's now solve more complex rational equations. You will be allowed to use the method of your preference (even if it is one not described here) but let's practice the two methods for the following equation: $$ Regardless of the method of your preference you need to find the Common Denominator. (Hint: When expressions in the denominator are factorable, it is very helpful to factor the denominators to find the correct Common Denominator) What is the Common Denominator in the equation above

da freeck kinda math is this just drop out

step-by-step explanation:

proportions are fractions that equal to each other. so if two fractions are the same, they are proportional.

let's check the answers to see if they are proportional.

question a is not proportional because you can't turn 1.5/3 to 3/9. if you try to multiply 1.5/3 by 2 or 3, you wont get 3/9. it's impossible to make the fractions the same.

question b is not proportional because you can't turn 22/33 to 4/6. 33 can't go into 6.

question c is proportional because when you multiply 2 and 3 by 71, you would get 142/213, and those fractions equal to each other

question d is proportional because when you divide 14 and 7 by 2, you would end up with 7/3.5, and those fractions equal to each other.
