You don't need a common denominator to multiply or divide fractions.
To multiply fractions, multiply the numerators and the denominators, e.g.:
1/2 x 3/5 = (1/3) / (2/5) = 3/10
To divide fractions, multiply the first fraction with the reciprocal of the second.
1/2 divided by 5/3 is the same as 1/2 times 3/5.
When the numerator and denominator of the division do not have a common factor.
No. Common denominators are needed for addition and subtraction, not multiplication or division.
A common denominator is 7.A common denominator is 7.A common denominator is 7.A common denominator is 7.
There can be no greatest common denominator. For supose x is the greatest common denominator. ie 24 divides x and 36 divides x. Then 2x is a common denominator and 2x > x so 2x is a greater common denominator than the greatest common denominator. That contradiction implies that there is no greatest common denominator.
The numerator goes in the division box.
No, You only need a common denominator when adding or subtracting fractions.
When the numerator and denominator of the division do not have a common factor.
Because it is not how multiplication or division are defined.
No. Common denominators are needed for addition and subtraction, not multiplication or division.
Because a common denominator of a set of numbers is a multiple - not a factor - of each one. A multiple, as might be expected from its name, requires multiplication, not division.
Addition and subtraction are the only fraction operations that need a common denominator. Multiplication, division, and exponents do not need a common denominator. In fact, it is best to use reduced fractions otherwise it gets very messy.
A common denominator is 7.A common denominator is 7.A common denominator is 7.A common denominator is 7.
To simplify complex fractions, first rewrite the complex fraction as a division of two fractions. Identify the numerator and denominator, and if necessary, find a common denominator for the fractions involved. Then, multiply both the numerator and the denominator by that common denominator to eliminate the fractions. Finally, simplify the resulting expression by reducing any common factors.
