You change the mixed fraction to an improper fraction . Then you find the denominators GCF. Then you subtract.
Another reply: Converting to an improper fraction is not really necessary, but converting to a common denominator is.
Example: 3 1/2 - 1 1/3 = 3 3/6 - 1 2/6 = 2 1/6. In other words, you can subtract the integer part and the fraction part separately.
Convert them to improper fractions and proceed.
Convert them to improper fractions with common denominators and proceed normally.
the fractions have different denominators
You need common denominators. Then add or subtract the numerators. If the answer is an improper fraction it is common practice to reduce it to a mixed number.
SUBTRACTION: You first turn both mixed numbers into improper fractions. If needed, change the denominators into like denominators. Next, subtract the two improper fractions and reduce if necessary. ADDITION: If needed, turn denominators so they are the same number. Next, add and reduce if necessary.
Make the denominators the same using equivalent fractionsAdd or subtract the numerators.Change the result to a mixed fraction if the numerator is larger thanthe denominator.Simplify the final result if possible.
To add or subtract mixed numbers, first convert them to improper fractions. Then, perform the addition or subtraction operation on the numerators while keeping the denominators the same. Next, simplify the resulting fraction if possible by reducing it to lowest terms. Finally, if needed, convert the improper fraction back to a mixed number for the final answer.
subtract a mixed fractor for a fifth grader
Convert them to improper fractions with a common denominator.
change the mixed # into a fraction
convert both to numbers with lowest common denominator then add
You make it into a improper fraction, then make a common denominator and remember to do what you did to the bottom to the top then solve
