You don't need a common denominator to divide fractions.
No only when adding or subtracting fractions a common denominator is needed
You don't need a common denominator to divide fractions.
No you do not.
No, you only need a common denominator when adding or subtracting fractions.
When you're dividing fractions ... or multiplying thrm ... they don't need to have the same denominator.
yes alot of times you do
Because it is not how multiplication or division are defined.
No. Common denominators are needed for addition and subtraction, not multiplication or division.
Option 1: Find a common denominator for the two fractions. It need not be the least common denominator; for example, for two fractions, if you just multiply the two denominators, you get a common denominator. Convert all the fractions to the common denominator. Then you can compare. Option 2: Convert each fraction to decimal, by dividing the numerator by the denominator. Then you can compare the decimals.
You basically have to learn separately how to do different things with fractions, including finding a common denominator; converting fractions to a different denominator; simplifying fractions; adding and subtracting fractions; multiplying fractions; dividing fractions.
by dividing the numerator by the denominator
No. Dividing fractions is achieved by inverting the divisor and multiplying the resulting fractions. To multiply fractions the numerators are multiplied together to form the new numerator and the denominators are multiplied together to form the new denominator.
