You do not but you are more likely to make mistakes if you don't.
Convert it to an improper fraction.
For a fraction, divide the numerator by the denominator and multiply by 100 for a percentage. If it's a mixed number, you first have to convert it to an improper fraction then do the same thing as for a fraction.
To convert a mixed number to an improper fraction, multiply the denominator by the whole number, add that total to the numerator and put the whole thing over the original denominator.
Change each mixed fraction to an improper fraction. Do this by multiplying the denominator by the whole number next to the fraction and then adding the numerator to the product you get. Once you do this, multiply fractions normally.
7/13 can't be converted into an improper fraction, since it's less than 1. Assume the given value is 7 1/3. This is in mixed number form. To convert it into improper fraction, you need to rewrite the term as the fraction of only numerator and denominator. For the numerator, multiply 7 by 3. Then, add that by 1. You should get: (7 * 3 + 1) / 3 = 22 / 3
turn fraction into a improper fraction
multiply the denominator by the whole number then add the numerator and you have an improper fraction
The simplest way is to rewrite the mixed number as an improper (top-heavy) fraction and then multiply the two fractions together as normal.For example, 2/7 * 1 1/4 = 2/7*5/4 = 10/28 = 5/14
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)
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.
Convert it to an improper fraction.
17/6 is an improper fraction. As a mixed number it is written 25/6.
turn the fraction upside down and multiplyConvert the mixed number to an improper fraction and multiply it by the reciprocal of the fraction.
Convert the mixed number to an improper fraction and proceed normally.
make each fraction a improper fraction the flip the second fraction and multiply straight across then simplify
The mixed number consists of a whole number and a fraction. Multiply the denominator of the fraction portion by the whole number and to this product add the numerator of the fraction portion. This value is the numerator of the new improper fraction. The denominator of the new improper fraction is the same as the denominator of the original fraction portion of the mixed number.
To convert a mixed number to an improper fraction, multiply whole number part by the denominator of the fraction part, then add the numerator to the product. The result is the numerator of the improper fraction. The denominator remains the same. For example, to convert 2 3/8 to an improper fraction, multiply 2*8 = 16, then add 3 to get 19. The improper fraction is 19/8.
