What is inverted in division of fraction?
The process of dividing two fractions is to invert the second one and multiply. 3/4 divided by 5/6 = 3/4 x 6/5
Why do you invert the divisor when you divide a fraction by a fraction?
Because that is just how it works mathematically If you divide one vulgar (or common) fraction by a second vulgar fraction, the rule is: Invert the second fraction and then multiply them together. It is too difficult to explain why this works, using typed explanation on the computer, but just accept that it works.
What do you turn the second fraction into in a dividing problem?
When dividing by a fraction, the second fraction (the divisor) is changed into its reciprocal by swapping the numerator and denominator over (turning it upside down) and then it is multiplied by the first number (fraction).

"Dividing Fractions is easy as pie, flip the second and multiply." Flip the second fraction, and multiply, and reduce.
How are reciprocals used when dividing fractions?
When dividing fractions, take the reciprocal of the second fraction, and multiply the first fraction by the reciprocal of the second fraction. Example: (a/b)/(c/d)=(a/b)*(d/c)
Why do you take the reciprocal of the second fraction when dividing?
Because division by a number (the second fraction) is the same as multiplication by its reciprocal.
How do you describe dividing fractions in two sentences?
Change the second fraction to its reciprocal. Multiply them.
How 2 divide a mixed number by a mixed number?
Change them into improper fractions. Invert the second fraction and multiply them together. Reduce if necessary.
