How to get rid of fraction in an equation?

Its really simple. In algebra whatever you do to one side you must do to the other side, period. This applies to adding, multiplying, dividing, squaring, etc

An equation is just that, two things that are the same. The simplest equation is 1=1 If you multiplying only the left side by 9 you would have 1=9 and in this universe, that is not true.

How to get rid of fraction in an equation?

When you are trying to get rid of an fraction in an equation you multiply the entire equation by a common denominator. Like if my equation is Y= (-4/9)^2 + (24/9)x +12, I would multiply the entire equation by 9 but my question to you all is do I multiply Y by 9 also? And make it 9y and if not, Why?...

Yes. If you change one side, you must do the exact same thing to the other. However, there is little need for finding a common denominator in this problem: (-4/9)^2 is going to give you 16/81. 24/9 is equal to 8/3.

To begin, rewrite the equation.

Y= (16/81) + (8/3)x + 12

8/3 is equal to 2 and two thirds. Add this on to 12.

14.667 + 2.667x = Y. Usually you want to avoid writing things like this in decimals, but writing proper fractions can be a bit difficult in a window such as this.

Multiply to get rid of fractions math errors 1/3*x = 1/4 3 * 1 / 3 * x = 3 * 1 / 4 3 / 3 * x = 3 / 4 x = 3 / 4

if you multiply an equation by a number, everything in that equation would have to be multiplied. so if you multiplied your equation by 9, then yes, you would get 9y = 9(-4/9)^2 + 9(24/9)x +12*9. but if you wanted to cancel out the fractions, you'd have you multiply your equation by 9^2 or 81, not just nine, because the coefficient of x^2 isn't 4/9, it's (-4/9)^2, or 16/81.

hope that helps!

Yes you do if you multiply both sides by 9 ALL TERMS are multiplied by 9 because of the distributive law.

However 9 is NOT the LCD. Notice you have (-4/9)^2 = 16/81

so if you choose to multiply by the LCD you will be multiplying by 81 and get.

81y = 16 + 24*9x +12*81

yes you have to multiply y also by 9. its like multiplying the whole equation by the comon denominator to get rid of it so both the sides of the equation are multiplied by the common denominator.

hope it helps.

Whatever you do to one side of the equation, you must do to the other side, to keep it balanced.
