(a/b) divided by (c/d)
=(a/b) x (d/c) <-- notice divisor is inverted (turned upside down)
now multiply both numerators and both denominators
= (ad)/(bc)

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.
Why is it possible to invert the divisor and multiply?
Because division and multiplication are mutually inverse operations.
How do you devide whole numbers by a fraction?
Invert the fraction, and multiply it by the whole number.
What is the invert and multiply rule in mathematics?
You may be referring to the rule for dividing fractions. To divide one fraction by another, you invert the second fraction (exchange numerator and denominator), and multiply instead.
What is the quotient when 5 of 8 is divided by 5 of 3?
To divide by a fraction, invert the divisor and multiply: 5/8 ÷ 5/3 = 5/8 x 3/5 = 3/8

How do you divide a fraction and amixed number?
Convert the mixed number into an improper fraction then divide the fraction and improper fraction as normal (invert the divisor and multiply) and simplify the result (including converting any improper fraction into a mixed number)
Why is it possible to invert the divisor and multiply?
Because division and multiplication are mutually inverse operations.
What steps do you take to divide a fraction by another fraction?
To divide one fraction (the dividend) by another (the divisor), invert the divisor and multiply the fractions together: eg 2/35 ÷ 4/5 = 2/35 × 5/4 = (2×5)/(35×4) = 10/140 = 1/14
How do you devide whole numbers by a fraction?
Invert the fraction, and multiply it by the whole number.

To divide by a fraction, invert the divisor and multiply: 5/8 ÷ 5/3 = 5/8 x 3/5 = 3/8
When you divide whole number by a fraction with a numerator of 1 how do you find the quotient?
Invert the fraction and multiply.
How so you divide fractions?
When dividing one fraction by another, invert the second fraction and multiply them.
What is 7 over 8 divided 3 over 5?
To divide by a fraction, invert the divisor and multiply: 7/8 ÷ 3/5 = 7/8 x 5/3 = 35/24 = 111/24
When do you flip the numerator and denominator?
When you wish to divide by a fraction, you would flip the divisor and multiply by the new fraction.
What is 8 over 1 divided by 3 over 4 in simplest form?
To divide by a fraction, invert the divisor and multiply: 8/1 ÷ 3/4 = 8/1 x 4/3 = 32/3 = 102/3
