No.
No.
You DO need a common denominator to add, subtract, or compare fractions. You DO NOT need a common denominator to multiply or divide fractions.
No, you do not need to find a common denominator when multiplying fractions. To multiply fractions, you simply multiply the numerators together and the denominators together. However, finding a common denominator can be helpful when simplifying the resulting fraction.

Yes. You need common denominators if you want to:Add fractionsSubtract fractionsCompare fractions ("which is larger?")You do not need common denominators to multiply or divide fractions. Thus, in the case of fractions, multiplication and division is actually easier than addition and subtraction.
You have to find a common denominator, multiply them, subtract them and then simplify if you need to.
No. Fractions don't need the same denominator in order to multiply them. The numerator of their product is simply the product of their numerators, and the denominator of their product is just the product of their denominators.
For subtracting and adding you cannot add or subtract unalike things. For multiplication and division you can multiply by whatever you want. In some maths you even multiply by variables such as "x". Or divide by them.
Assuming the fractions are "normalized" (the fractional part is less than 1): First compare the integer part. If the integer part is the same, you need to compare the fractions. If the denominator of the fractions is different, you have to convert to a common denominator. The simplest way to find a common denominator is to multiply both denominators (i.e., you don't need the LEAST common denominator - any common denominator will do).
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.
You do not need to.
no u dnt need to have a common denominator.. Just multiply both the denominator and numerator of the fractions u are working on and u will arrive at the answers
