You need to find a common denominator. Then you need to convert them to equivalent fractions with this common denominator.

What are the rules for subtracting fractions?

You multiply the fractions until the denominators are equal. Then, you subtract.


What are the step in subtracting disimilar fraction?

Same as for adding: If the denominators are not equal, you must first find a common denominator, then convert both fractions to that common denominator.


How do you know when two fractions are equal?

If the denominators (bottom numbers) are not equal, making equivalent fractions of them so that the denominators are equal. With the denominators equal if the numerators (top numbers) are equal, then the fractions are equal.


How are equivalent fractions used in renaming when subtracting?

When subtracting one fraction to another, one or both fractions are renamed so that they have the same denominators. Then the result of the subtraction is the equal to the subtraction of the numerators divided by the common denominator.


When you add or subtract fractions with unlike denominators why do you have to find LCM?

Because to add fractions, the denominators must be equal.

When is the lcd of two fractions equal to product of denominators?

When the denominators are relatively prime, that is, they have a GCF of 1.


Two or more fractions that are equal is called what?

In actual problems, we convert two (or more) fractions so that they have equal denominators.


What do you notice when the denominators in two fractions are the same?

You can represent the two fractions with one fraction with a numerator equal to the sum of the two individual numerators (with sign) and a denominator equal to just one of the two denominators.


Why dosent 1over2 1 over 3 equal 2over5?

Because when adding or subtracting fractions the denominators must be the same by finding the lowest common denominator and changing the numerator accordingly so 1/2+1/3 becomes 3/6+2/6 = 5/6


Can two fractions with the same numerator and different denominators be equal?

Only if the numerator is zero,


What do you do when you're going to subtract fractions but the numerator is the same?

Whether the numerators are the same or not, you need to get the denominators to be the same. First, find the least common denominator. Then convert the fractions to equal fractions that use the common denominator. Then you can subtract the fractions by subtracting the numerators. Finally, look for common factors between the numerator and the denominator of the difference in order to put the answer in simplest terms.


How do you find equivalent fractions?

first simplify the fraction then multiply the denominators times the numerators and see if they are equal

What are equilavent fractions?

Equivalent fractions can be defined as fractions that may have different numerators and denominators but they represent the same value. For example, 9/12 and 6/8 are equivalent fractions because both are equal to 3/4.

How do you add two fractions with a different denominator?

You add two fractions with a different denominator by multiplying the denominators by a number that will make them equal. Be sure to multiply the numerator by that number too.

What do you do to add fractions with common denominators?

To add fractions with the same denominators, simply add together the numerators, and cancel down if necessary. For example, 5/8 + 1/8 = 6/8. Cancelling this down to an improper fraction in its simplest form, this is equal to 3/4.


What is the definition for Properties of equality?

I think its a property in which both sides of an equation are equal either by adding, subtracting, multiplication, or division.
