Why do you need a common denominator when adding and subtracting fractions but not when you multiply or divide fractions?
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.
When doing fractions why is it easier to multiply and divide fractions than add and substract fractions?
It is easier to multiply or divide fractions than to add or subtract fractions because in multiplication, you just have to multiply the numerator by the numerator and the denominator by the denominator. Same applies with division of fractions, except that you have to reciprocate the fraction you're dividing with (divisor) then proceed to multiplication. Whereas, in addition and subtraction of fractions, you still have to get their Least Common Denominator (LCD).
