Subtraction with Mixed Numbers and Fractions Worksheet

Mixed numbers and fractions 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 subtracting a fraction from a mixed number or subtracting a mixed number from a fraction.

How to Use this Worksheet

In this sixth grade fraction worksheet, students are required to find the difference by subtracting a fraction from a mixed number or subtracting a mixed number from a fraction. Convert the mixed number to irregular fraction, 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 difference between the numerators. The difference of numerators divided by the common denominator is the difference of mixed number and fraction.
