How do you divide fractions with common denomonators?
switch numbers and multiply you should know that
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.

Why do you invert fractions?
