Adding or Subtracting a Mixed Number to/from Whole Number Worksheet

Mixed and whole numbers addition and subtraction worksheet with answers to practice & learn 6th grade math problems is available online for free in printable & downloadable (pdf & image) format. Tap on PRINT, PDF or IMAGE button to print or download this grade-6 fraction worksheet to practice adding mixed number and whole number or subtracting a mixed number from whole number or subtracting a whole number from mixed number.

How to Use this Worksheet

In this sixth grade fraction worksheet, students are required to find the sum of or difference between mixed number and whole numbers. Convert the mixed number and whole number to their equivalent fraction form, find the LCM or LCD of denominators, multiply LCD with both numerator and denominators of each fraction, simplify the fractions to have like denominators and find the sum of or difference between the two numerators. The sum of or difference of numerators divided by the common denominator is the resulting fraction of these given mixed and whole number.
