You can find a common denominator by multiplying together the denominators of your fractions. For example, try 13 * 15 = 195 (you don't need to use the 5 because anything divisible by 15 will also be divisible by 5). You know that 195 is divisible by 13 and 15 (because those are the two numbers you multiplied together to get it), and by 5 because 195 ends in a 5. Now convert the numerators so you have equivalent fractions: 5/13 = 75/195 2/5 = 78/195 7/15 = 91/195 So 7/15 is the greatest. But sometimes it's easier just to convert your fractions to decimals by dividing the numerators by the denominators: 5/13 = .38461538461538 2/5 = .4 7/15 = .46666666666666 (repeating forever)
