How do you solve fractions that equal each other with variables?
Correct answer: To solve an equation with a variable in a fraciton, treat the denominator as a constant value and multiply both sides of the equation by the denominator in order to eliminate it.
How do you solve algebraic fractions?
When adding or subtracting algebraic fractions, the first thing to do is to put them onto a common denominator (by cross multiplying). When solving equations containing algebraic fractions, first multiply both sides by a number/expression which removes the fractions.
What is an equivalent algebraic fraction?
If the numerator and denominator of a fraction are multiplied (or divided) by the same nonzero number, then the resulting fraction is equivalent to the original fraction.
How do you find equivalent algebraic expressions?
Combine any like terms on each side of the equation: x-terms with x-terms and constants with constants. Arrange the terms in the same order, usually x-term before constants. If all of the terms in the two expressions are identical, then the two expressions are equivalent.
What is it called when both sides of an equation are equal?
Sometimes people refer to this as keeping the equation “balanced”. If you think of an equation as being like a balance scale, the quantities on each side of the equation are equal, or balanced.
How do you solve a fraction equivalent of a fraction?
To find equivalent fractions, we multiply the numerator and the denominator by the same number, so we need to multiply the denominator of 7 by a number that will give us 21. Since 3 multiplied by 7 gives us 21, we can find an equivalent fraction by multiplying both the numerator and denominator by 3.
How do you find the equivalent fraction of an equation?
Multiply the numerator and denominator by the same number. For instance, if we take the fraction 4/8 and multiply both the numerator and denominator by 2, we get (4×2)/(8×2) = 8/16. These two fractions are equivalent.
