This is because dividing by a number is the same as multiplying by its reciprocal.
It is called "taking the reciprocal".
Unless the first number is zero, then this must ALWAYS be the case.
You switch its numerator(top number) with its denominator(Bottom number)
you switch the second fraction around ( multiply by the reciprocal ) because it is way easier than trying to actually divide the fraction by dividing, you get the same answer. but we multiply by the recipricol because multiplying fractions is simpler. example.... 4/6 divided by 8/5 you then get 4/6 * 5/8 = 5/12
First the number needs to be changed in appearance from 4 3/4 to 19/4. Then the numerator and the denominator need to switch places.Then you get the reciprocal, which is 4/19.
Take the 2nd fraction, switch the denominator with the numerator, multiply across, simplify.
you switch the numerator with the denominator then multiply the numerator first then the denominator.
You Switch The Numerator & Denominator of the second fraction and then you change the division to multiplication. For example: 1/2 divided by 2/3 becomes 1/2 times 3/2, and you would multiply straight across (numerator by numerator and denominator by denominator) to get 3/4.
Reciprocal
Taking the reciprocal.
inversion
Switch the numerator with the denominator.
it is called a reciprocol
It is called "taking the reciprocal".
The resulting number is the reciprocal of the original number.
16 / 9 To find the reciprocal simply switch the numerator and the denominator with one another.
Unless the first number is zero, then this must ALWAYS be the case.
