Why don't you need a common denominator to multiply and simplify a fraction?

You could, but it would add extra steps and wouldn't change the answer.
2/3 x 4/5 = 8/15
2/3 = 10/15
4/5 = 12/15
10/15 x 12/15 = 120/225
120/225 = 8/15

How do you subtract a fraction?
Find a common denominator (make sure you multiply BOTH the numerator and the denominator) then subtract the numerators and simplify if necessary.
Show me how do you simplify a fraction then write into a fraction?
All you have to do is find the Greatest Common Factor (GCF) of the numerator and the denominator then divide the fraction by the GCF to simplify a fraction. Hope this helps
How do you solve simplify fractions?
You search for common factors in the numerator and the denominator. Then you divide numerator and denominator by this common fraction. For example, in the fraction 9/12, the common factor is 3. If you divide numerator and denominator (top and bottom) by 3, you get 3/4, which is an equivalent fraction.
How do you simplify an expression that contains a fraction bar?
If there is a common factor between the numerator and the denominator, you can eliminate it. Otherwise, there is usually not much to simplify.
What is the fastest way to simplify a fraction?
Divide both the numerator and the denominator by their greatest common factor.

Is a fraction or a ratio by dividing the numerator and denominator by a common factor?
Dividing the numerator and denominator by a common factor is how you simplify a fraction.
What do you do to the numerator in a lowest common denominator problem?
Multiply the numerator of the fraction by the same amount that you multiply the denominator of that fraction.
How do we know the fraction is simplify?
When the GCF of the numerator and the denominator is 1.

How do you subtract two fractions?
You have to find a common denominator, multiply them, subtract them and then simplify if you need to.
How do you subtract and simplify fractions?
find a common denominator. multiply the top and bottom by it. then you can combine the numerators over the same denominator

How do you make the denominator the same?
To make the denominator of two fractions the same, you multiply numerator and denominator of one fraction of the fractions by the same number. You may also have to multiply numerator of the other fraction by a different number.For example, to add 1/8 + 1/10, you have to convert to a common denominator; the lowest common denominator is 40, but any common denominator will work (for example, 80 which is simply the product of the two).To convert 1/8 to a fraction with a denominator of 40, multiply numerator and denominator by 5. To convert 1/10, multiply numerator and denominator by 4. The result is:5/40 + 4/40To make the denominator of two fractions the same, you multiply numerator and denominator of one fraction of the fractions by the same number. You may also have to multiply numerator of the other fraction by a different number.For example, to add 1/8 + 1/10, you have to convert to a common denominator; the lowest common denominator is 40, but any common denominator will work (for example, 80 which is simply the product of the two).To convert 1/8 to a fraction with a denominator of 40, multiply numerator and denominator by 5.

How would you use the multiplication rule to find common denominators?
multiply the nominator and denominator of each fraction by the denominator of the other fraction
