Because division and multiplication are mutually inverse operations.
(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)
When you divide by fractions, you invert and multiply.
" ... multiply by the RECIPROCAL of the divisor.
invert and multiply
To divide by a fraction, invert the divisor and multiply: 5/8 ÷ 5/3 = 5/8 x 3/5 = 3/8
You turn the mixed numbers into improper fractions. Then invert the divisor and multiply the numerators, and multiply the denominators (because division by a fraction is multiplication by its inverse) and simplify if possible: Example: Problem 3 1/4 divided by 2 1/2 - improper factions 13/4 divided by 5/2 - invert second fraction 5/2 to 2/5 - multiply 13/4 x 2/5 = 26/20 which is equivalent to 13/10 or 1 3/10
A divisor is the greater number that is divided by the dividend number. A dividend is a number that is divided by he divisor or multiply
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.
because the divisor wont work when you multiply it??
Multiply the reciprocal of the divisor by the dividend.
What is the largest remainder possible if the divisor is 10
To divide by a fraction, invert the divisor and multiply: 5/6 ÷ 15/1 = 5/6 x 1/15 = 5/6x3x5 = 1/18
