45Find which is bigger or smaller fraction worksheet with answers for 6th grade math curriculum is available online for free in printable and downloadable (pdf & image) format. Tap on PRINT, PDF or IMAGE button to print or download this grade-6 fractions worksheet to practice comparing unlike fractions.

In this sixth grade fractions worksheet, students are required to compare two unlike fractions to find which is bigger or smaller fraction. For fractions with unlike denominators, find the LCD of denominators, multiply LCD with both numerator and denominator of each fraction, simplify the fractions to have equal denominators and compare the numerators. The numerator with greatest value is the bigger fraction. Similarly, the numerator with smallest value is the smaller fraction in the comparison.

Teachers, parents or students can check or validate the solved questions by using the corresponding answers key which comprises the step by step work on how to find the biggest or smallest fraction by unlike fraction comparison.

Students, teachers or parents can generate unlimited set of questions and answers by using this "**NEW WORKSHEET**" button to prepare exam, assignments, classwork or homework problems on unlike fractions comparison by using LCM or LCD method.
