This is because dividing by a number is the same as multiplying by its reciprocal.
When dividing fractions with different denominators, first, you multiply the first fraction by the reciprocal of the second fraction. To do this, you switch the numerator and denominator of the second fraction. After that, you multiply the numerators together and the denominators together to simplify the result. Finally, simplify the resulting fraction if possible.
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
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.
Taking the reciprocal.
Switch the numerator with the denominator.
inversion
Reciprocal
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.
