What is the rule for subtracting fractions?
First, change it so that the two fractions have the same denominator (by changing the fractions into equivalent fractions). Once the two fractions have the same denominator, it is simply a case of subtracting the numerators, leaving the denominator the same. Finally, reduce the fraction to its lowest terms (if possible).
What is the definition of quick common denominator?
it means when two denominators can reduce fast
How do you know if you should reduce a fraction or not?
You should reduce a fraction if the numerator and denominator have any common factor greater than one.
How do you reduce fractions to simplest terms?
You divide both the numerator and denominator by a common multiple.
How would you explain mixed numbers changing into an improper fraction?
Multiply the denominator by the whole number. Add the numerator to that total. Put that sum over the original denominator.

What is the process of changing a fraction to a decimal?
divide the denominator by the numerator
When can you reduce and cross reduce?
to reduce you you have to find the two numbers lowest common denominator. Then that is the number that is reduced over the number you got.
How do you reduce 4-8?

Reduce 2100 to the least common denominator?
That's not really how that works...
What is the rule for changing mixed fractions to improper?
Multiply the denominator by the whole number, add the numerator, and put that total over the denominator.
Do you leave the denominator alone for mixed numbers?
Yes. when changing a mixed number to another form you leave the denominator constant and it does not change.

How do you know if you should reduce a fraction or not?
You should reduce a fraction if the numerator and denominator have any common factor greater than one.
What is used in changing dissimilar fractions to similar fractions?
Finding the lowest common denominator
How can you tell that a fraction is in its simplest form?
When you can no longer reduce the numerator and denominator by the same number.
How do you reduce fractions to simplest terms?
You divide both the numerator and denominator by a common multiple.
