Three easy steps-

First, you change the mixed fraction into an irregular one(big numerator)

Then you find a common denominator (same multiple/number) with the 2 fractions

Lastly, you divide =D

You change the mixed fraction to an improper fraction, so 1 and 3/4 would become 7/4. Then you multiply it by the reciprocal of the regular fraction. If the regular fraction were divided by 3/4, it would be multiplied by 4/3.

you turn the mixed fraction into a top heavy fraction eg 1 and 3/4 = 7/4

u then flip the second fraction and change the divide to a multiply

eg 1 and 1/2 divided by 3/4 = 7/4 x 2/1

btw im 14 and in top set for maths

You need to turn the mixed fraction into a regular fraction. For example, 7 3/4 would become 31/4.

Then, turn the second fraction (the one you're dividing by) upside down, and multiply the two fractions together.

(31/4) / (5/4) = (31/4) x (4/5) = 31/5

OH! I learned that in 5th grade! What you do is take the mixed # and make it into an improper fraction! (hopefully you know how to do that. It is kinda tough to explain by typing! SRY! ♥) then you take the regular fraction and divide! you have to find the reciprocal (ex: reciprocal of 5/6 is 6/5) (youflip the numerator and denomenator) then you multiply! kinda confusing! heres an example:

7/9 (divided by) 6/8 equals: 1and 1/27 (i might be wrong)
7/9 (times) 8/6 (reciprocal)

A mixed fraction is of the form (K + p/q) where all three (K, p and q) are integers.

You can change it with these steps:

K(q/q) + p/q (multiplying K by q/q does not change K's value because q/q is one.

qK/q + p/q

Put everything on the same denominator

(qK + p)/q

Next: dividing by a fraction is the same as multiplying by the inverse of the fraction.

dividing by a/b is the same as multiplying by b/a

So, if your original problem was:

[ K + p/q ] / (a/b)

you can rewrite it as

[ (qK + p) / q ] * (b/a)
b(qK + p) / qa

example:

1 3/5 divided by 2/7

8/5 divided by 2/7
8/5 multiplied by 7/2
(8*7) / (5*2)
56 / 10

5 6/10
5 3/5

convert the mixed fraction to improper fraction then divide
ex : 1 2/3 = 5/3

a regular fraction is just the number over 1, 3=3/1
the easiest way is to do the old invert and mutiply

5/4 divided by 3 equals 5/4 x 1/3 1x5=5, 4x3=12
5/4 divided by 3 equals 5/12

you must make the mixed number into an improper fraction, then you reciprocal next number (ex. for reciprocal: 2/3=3/2, 5/6=6/5 etc.) then you actually do multiplcation for example

1 1/2 dived by 5/6
do 3/2 times 6/5
then figure out the answer

I just did this today

make the mixed fraction an improper fraction and then change it back to a mixed number when you solved the problem.
