Unlike Fractions Comparison Worksheet

Find 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.

How to Use this Worksheet

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.
