It's much easier to multiply fractions than it is to multiply mixed numbers.
Try either one some time.
You do not do anything. An improper fraction IS a real number.
You can't. Improper and proper fractions are two different things. You can convert an improper fraction to a mixed number.
You take the bottom number and divided by the top number.
To divide mixed numbers, first convert each mixed number into an improper fraction. For example, convert (2 \frac{1}{3}) into (\frac{7}{3}) by multiplying the whole number by the denominator and adding the numerator. Next, take the reciprocal of the second improper fraction and multiply it by the first. Finally, simplify the resulting fraction if possible.

As an example , let the improper fraction be '3/2' . For any fraction, of any number, the denominator (bottom) is divided into the numerator(top) So for 3/2 , you divide '3' by '2'. This gives an answer of '1' and a remainder of '1'. The answer of '1' is the coefficient(large number at the start of the fraction), and the remainder of '1' becomes the numerator of the fraction over '2' the denominator. Hence 3/2 = 1 1/2. Similarly 5/4 = 1 1/4 Similarly 18/7 = 2 4/7 et seq/.
When working with mixed numbers it is almost always easier to convert them to improper fractions first, do the whatever (with the improper fraction just like an ordinary fraction) and convert any final improper fraction into a mixed number. To convert a mixed number to an improper fraction, multiply the whole number by the denominator and add the numerator to form the new numerator and keep the denominator the same. For example: 2 3/7 → (2x7+3)/7 = 17/7 To convert an improper fraction to a mixed number divide the numerator by the denominator to get a whole number quotient and a remainder. The whole number quotient is the whole number and the remainder is put as the numerator over the original denominator as the fraction. For example: 17/7 → 17 ÷ 7 = 2 r 3 → 17/7 = 2 3/7
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)
Cancellation cannot be used to convert a mixed number into an improper fraction.
As an example 2 3/5 X 7 First convert the mixed number to an improper fraqction Hence 2 3/5 = 13/5 Next we convert the '7' to an improper fraction by placing it over a trivial '1'. Hence '7' = '7/1'. Re-writing 13/5 x 7/1 We separate;y multiply the numerators together, and the denominators together. Hence 13/5 X 7/1 = 91/5 Finally we convert the improper fraction back to a mixed fraction by dividing by '5' , which will give an answer of '18' and a remainder of '1' Hence it is re-written as ' 18 1/5 '. The answer. NB Whenthe numbers become large , look to see if you can cancel down /reduce. So amending the above numbers slightly. 2 3/5 X 5 = > 13/5 X 5/1 In this case '5' is a common factor ; top & bottom'. so we cancel down by '5' Hence 13/1 X 1/1 proceeding as before. 13 / 1 = 13 The answer!!!!! These methods are good for any set of frqactional numbers.
To convert an improper fraction to a mixed number, divide the denominator into the numerator. The answer is the whole number. Put any remainder over the original denominator to create the fraction part.
You take the bottom number and divided by the top number.
Convert the mixed number to an improper fraction and proceed.
5/3 is 1.6666666667 as an improper fraction.
To divide mixed numbers, first convert each mixed number into an improper fraction. For example, convert (2 \frac{1}{3}) into (\frac{7}{3}) by multiplying the whole number by the denominator and adding the numerator. Next, take the reciprocal of the second improper fraction and multiply it by the first. Finally, simplify the resulting fraction if possible.
