addition of mixed fractions
Example: 13 2/5 + 16 1/2
1. Change the mixed fractions to improper fractions
13 2/5 = [(5 * 13)+2]/5 = (65+2)/5 = 67/5
16 1/2 = [(2 * 16)+1]/2 = (32+1)/2 = 33/2
2. Find their LCD (Least Common Denominator) and then do the addition.
67/5 + 33/2
= (134 + 165)/10
= 299/10 or 29 9/10
Change them into mixed numbers and add the integers and fractions together ensuring that the fractions have a common denominator.
Yes.
To add mixed numbers with like denominators, first add the whole numbers, then add the fractions. For example: 2 2/3 + 4 1/3 = ?? First add the whole numbers. 2 2/3 + 4 1/3 = 6? Then add the fractions. 2 2/3 + 4 1/3 = 6 3/3 Simplify. 3/3 is one. 2 2/3 + 4 1/3 = 6 + 1 = 7.
Mixed numbers can be converted to improper fractions. Improper fractions can be added the same way proper fractions are.
3 and 3/4
Change them into mixed numbers and add the integers and fractions together ensuring that the fractions have a common denominator.
Yes.

Mixed numbers can be converted to improper fractions. Improper fractions can be added the same way proper fractions are.
To find the sum of two mixed numbers, turn the mixed numbers into improper fractions (multiply the base with the denominator and add the numerator), then add the two fractions. To add the two fractions, find the LCD (lowest common denominator) and add the two numerators, but leave the denominators the same.
irregular fractions! ex. if the equation is 2 3/4, you would multiply 2*4, then add three. that is your numerator, denominator will stay the same. it will =11/4
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.
3 and 3/4
Same as any average. Add all the fractions and divide them by the amount of fractions
First you need to change to improper fractions: so: 16/3 and 4/3 and then add the numerators: =20/3 ( changed back to mixed fractions:) 6 2/3
It is best to convert the mixed fraction to an improper fraction. They are then added together in the same way as proper fractions are added together.
you can't add nor subtract mixed fractions so you need to turn it into a fraction, if you wanna turn a mixed fraction into a fraction you need to multiply the whole number by the denominator, then add the numerator, then you can multiply normally (make sure you simplify and turn it into a mixed fraction your answer)
