How do you convert mixed numbers to fractions?
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.
Steps for multipling fractions and mixed numbers?
to multiply fractions add them together and reduce the final fraction. to multiply mixed numbers, first make the mixed number an improper fraction, by mulitplying the whole number and the denominator and adding the answer to the numerator. Example: The improper fraction 8/5 can be changed to the mixed number 1 3/5 by dividing the numerator (8) by the denominator (5). This gives a quotient of 1 and a remainder of 3. The remainder is placed over the divisor (5).
How do you subtract mixed fractions?
convert them to Improper Fractionthen substract them (using substraction of Fractions)then convert back to Mixed Fractions.consider two mixed fractions, say, ab/c and xy/z.now u want ab/c - xy/z ?first convert mixed fractions to improper fractions.ab/c becomes, (ca+b)/c and xy/z becomes, (zx+y)/z.now, (ca+b)/c-(zx+y)/z is what we want.take LCM, {z(ca+b)-c(zx+y)}/czthis will be the answer.Example: What is 15 3/4 - 8 5/6 ?Convert to Improper Fractions: 15 3/4 = 63/48 5/6 = 53/6Common denominator of 12:63/4 becomes 189/1253/6 becomes 106/12Now Subtract:189/12 - 106/12 = 83/12Convert back to Mixed Fractions:83/12 = 6 11/12Converting improper fraction to mixed fraction:83/12 = (72+11)/12= 6 11/12Divide the numerator by the denominator.Write down the whole number answerThen write down any remainder above the denominator.
Multiplying fractions and mixed numbers?
can't do it as is... you must convert the mixed number to an improper fraction to multiply To convert the mixed number to a fraction you multiply the denominator and the number in front and then add that to the numerator then you put that number over the original denominator ex. 2 1/3 = (3 x 2 + 1)/3 =7/3 then you can multiply: 7/3 X 4/5 = 28/15
