c23Comparing - Step 1If the denominators are the same, then the fraction with the larger numerator is greater.3/5 is greater than 2/5

4Comparing - Step 1If the numerators are the same, then the fraction with the lower denominator is greater.1/8 is greater than 1/12

1/8

1/125

LCDLeast Common DenominatorThe least common denominator is the least common multiple of the two numbers

10 is the LCM3 2 54 ; 3 ; 612 is the LCMComparing - Step 2If the denominators and numerators are different, than a common denominator should be found.7Comparing - Step 2If the denominators and numerators are different, than the least common denominator should be found.

8Comparing - Step 2If the denominators and numerators are different, than the least common denominator should be found.

An easy way to do this is to find LCM using the ladder systemx 2x 59Comparing - Step 2If the denominators and numerators are different, than the least common denominator should be found.An easy way to do this is to find LCM using the ladder system

x 2x 5

10Comparing - Step 3Since a common denominator was found by LCM (using ladder system), the same number must be multiplied to the numerator

x 2x 5

11Compare - Final StepCompare the new numerators and you will find the greater fraction.
