Addition Mixed and Whole Numbers Worksheet

Mixed and whole numbers addition 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 whole number with mixed number or adding mixed number with whole number.

How to Use this Worksheet

In this sixth grade fraction worksheet, students are required to find the sum of mixed and whole numbers for each problem of this worksheet. Convert the mixed number to its equivalent irregular fraction, convert the whole number to its equivalent fraction form, find the LCM or LCD of denominators, multiply the LCD with both numerator and denominator of each fractions, simplify the fractions to have equal denominators and add the numerators. The sum of numerators divided by the common denominator is the sum of whole and mixed numbers.
