How do you write equivalent fractions with the lowest common denominator?
Well, isn't that just a happy little question! To write equivalent fractions with the lowest common denominator, you first find the least common multiple of the denominators. Then, you rewrite each fraction using that common denominator. It's like painting a beautiful landscape - just take your time, follow the steps, and soon you'll have a lovely set of equivalent fractions.
Why is it important to learn about equivalent fractions?
Answer: When adding or subtracting fractions with different denominators it is important to change the denominators into the lowest common denominator by using equivalent fractions. Answer: Equivalent fractions are used to: * Simplify fractions. It is sort of inelegant to write the final solution of a problem as 123/246, when you can just as well write it as 1/2. * Add fractions. If two fractions have different denominators, you need to convert them to equivalent fractions that have the same denominator. Only then can you add. * Subtract fractions (same as addition). * Compare fractions, to check which one is larger (same as addition).
How do you minnous fractions?
Subtracting fractions is similar to adding fractions. If the fractions have the same denominator, you subtract the numerators. If the fractions have different denominators, you have to convert to a common denominator first.Subtracting fractions is similar to adding fractions.

Why can you multiply the numerator and the denominator of a fraction by the same number to write an equivalent fraction?
Because that is how equivalent fractions are defined!
How do you write the Simplest form of fractions?
Factor the numerator and denominator, and then cancel any common factors.
How do you write equivalent fractions for a fraction?
Multiply the numerator and the denominator by the same counting number.
Why is it helpful to write a number as a product of prime?
When adding or subtracting fractions with different denominators finding the prime product of each denominator helps in finding the lowest common denominator of the given fractions by their lowest common multiple.
How do you write fractions as equivalent fractions with the LCD?
(1) find the LCD. (2) find the factor that each original denominator needs to be multiplied by to get the LCD. (3) multiply both the numerator and the denominator by that factor.
How do you Add and Subtratc fractions mixed with the same denominators and Different denominators?
Different denominators: First, you find a common denominator (it can be the least common denominator, or any common denominator), and convert all fractions involved to equivalent fractions, using the common denominator. For example, 1/4 + 2/3. 12 is a common denominator; you can write this as 3/12 + 8/12.Same denominator: Just add (or subtract) the numerators, and keep the denominator. The above addition would become 11/12. Finally, you may want to check whether you can simplify the answer. Depending on how you (or the teacher) prefers the answer, you may also want to convert to a mixed fraction. In the above example, no such simplification is possible.
How do you write a fraction in an equivalent form?
Select any integer greater than 1 or any common factor of both numerator and denominator. If that number is p then the fractions x/y and px/py are equivalent.
Why do you need like denominators to add and subtract fractions?
Finding a common denominator makes it possible to add two fractions because it allows us to write each fraction as a multiple of a common (usually smaller) fraction. Subtracting fractions works the same way; find a common denominator so that the fractions involved are in the same terms.
Why is it helpful to write a number as a product of primes?
Because it helps in reducing fractions to their simplest terms and finding the lowest common denominator when adding or subtracting fractions
