this fraction worksheet is great for practicing adding mixed numbers problems. the problems may be selected for five different degrees of difficulty. the easiest will keep the denominators the same and the numerators between 1 and 9. the hardest will keep the numerators between 1 and 20 and the common denominators under 120. the answer worksheet will show the progression on how to solve the problems. first find the common denominator and adjust the fractions. the next step is to add the numerators and the whole numbers. then check to see if we need to simplify or reduce the mixed number. this fraction worksheet will generate 10 or 15 mixed number addition problems per worksheet, and remember every time you create a worksheet the problems will change and will not repeat. numerators 1 thru 9.        denominators 1 thru 12.        both fractions have the same denominator. numerators 1 thru 9.        denominators 2, 3, 4, 5, & 10. numerators 1 thru 12.        common denominators up to 30. numerators 1 thru 16.        common denominators up to 60. numerators 1 thru 20.        common denominators up to 120.
