All you do is compare the numerators to see which fraction is greater, like this : Same Denominators 4Ĭomparison withDenominators Comparing Fractions with Different DenominatorsĬomparing fractions with different denominators requires a fiddling more exercise ( unless you use the compare fractions calculator on this page ), because in order to compare the fractions you must first turn their different denominators into the same denominators. Reading: Compare Fractions Calculator to See Which Fraction is Greater Comparing Fractions with Same DenominatorsĬomparing fractions with the same denominators ( buttocks number ) is easily.
We turn 3 / 4 into a decimal by dividing 3 by 4. We turn 2 / 5 into a decimal by dividing 2 by 5. The larger the decimal number, the larger the fraction.įor example, here we have the fractions 2 / 5 and 3 / 4. Fractions can be turned into decimals by dividing the numerator by the denominator. Ĭomparing Unlike Fractions using DecimalsĬonverting unlike fractions to decimals is a method that can be used to compare the size of them. īoth fractions have the same denominator and can now be ordered.Ģ0 is less than 27 and so, 20 / 6 is less than 27 / 6. Here is another example of comparing the size of two improper fractions.
Ģ5 is a larger numerator than 24 and so, 25 / 20 is larger than 24 / 20. Writing the fractions as equivalent fractions with denominators of 20, 5 / 4 = 25 / 20 and 6 / 5 = 24 / 20. 20 is the first number in both the 4 and 5 times table.
The common denominator of these fractions is 20. Improper fractions are simply fractions that have a larger numerator on top than their denominator on the bottom. Two improper fractions can only be compared if they have the same denominator on the bottom.įor example, here are the improper fractions of 5 / 4 and 6 / 5. The largest improper fraction will now have the largest numerator. To compare improper fractions with different denominators, first write each fraction as its equivalent fraction so that they both have the same denominator.

How to Compare Improper Fractions with Different Denominators The arrow of the sign points to the smaller fraction. Therefore we can say that 3 / 4 is less than 7 / 8. Now that both fractions are out of 8, we can compare them.Ħ is less than 7 and so, 6 / 8 is less than 7 / 8. We double the numbers in the first fraction so that 3 / 4 = 6 / 8. We can see that 8 is the first number in the 4 and 8 times table. Here is another example of comparing fractions with different denominators. We can write this as 1 / 4 ‘ always opens up to face the larger fraction and points at the smaller fraction. This allows us to compare the original fractions. Step 3 is to compare the fractions using their numerator.ģ is less than 4 and so, 4 / 12 is less than 3 / 12. Step 2 is to write both fractions as equivalent fractions with a common denominator. We will use 12 as the common denominator. However We can see that 12 is a number that appears first. We only need to list the numbers up to 24 because 4 × 6 = 24.
Step 1 is to find the first number to appear in the times table of both denominators.
