How does dividing a number by a fraction involve multiplication?
When dividing by a fraction, the answer is obtained by multiplying by the reciprocal.
How is multiplying of fractions simialar to dividing of fractions?
In multiplication and division of fractions, both involve multiplication. This is their similarity. In multiplication of fractions, multiply the numerator by the numerator of the other fraction and the denominator by the denominator of the other fraction. Example: 1/2 * 2/3 = 2/6 In division of fractions, reciprocate the divisor then follow the step in multiplying fractions. Example: 1/2 ÷ 2/3 = 1/2 * 3/2 = 3/4
Why is there no common denominator when multiplying or dividing fractions?
Because it is not how multiplication or division are defined.
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).

Because it is not how multiplication or division are defined.
What is one step when multiplying fractions?
Multiplication of fractions is similar to multiplication of whole numbers. Often, multiplication of fractions can be made easier by first performing cancellation. Cancellation involves dividing both a numerator and a denominator by the same number. This is the same as dividing a fraction by one, and so it does not alter the answer. When cancelling, cross out the old terms and write in the new terms.
How does mixed number compare with dividing fractions?

When dividing fractions do need a common denominator?
No. Common denominators are needed for addition and subtraction, not multiplication or division.

Why do you need to find the reciprocal of the divisor when dividing a fraction?
It is not just in fractions. In general, division can be defined as multiplication by the reciprocal. For example, dividing by 5 is the same as multiplying by 0.2. However, it is mainly in calculations with fractions that this is normally used as a practical way of doing the calculations.
