Compare 9/10 and 11/15

Comparing fractions like 9/10 and 11/15 involves determining which fraction is greater or if they are equal. Here are the steps to compare these fractions:

Step 1: Find a Common Denominator

The first step is to find a common denominator for the fractions. The denominator is the bottom number in a fraction. A common denominator is a number that both denominators can divide into without a remainder. In this case, the denominators are 10 and 15. The smallest common multiple of 10 and 15 is 30. Therefore, 30 will be our common denominator.

Step 2: Convert the Fractions

Next, convert each fraction to an equivalent fraction with the common denominator.

To convert 9/10 to a fraction with a denominator of 30, multiply both the numerator (top number) and the denominator by 3. This gives:

To convert our second fraction 11/15 to a fraction with a denominator of 30, multiply both the numerator and the denominator by 2. This gives:

Step 3: Compare the Numerators

Now that the fractions have the same denominator, you can directly compare their numerators.

The numerators are 27 for 27/30 and 22 for 22/30.

Step 4: Determine the Larger Fraction

The fraction with the larger numerator is the greater fraction.

Since 27 (numerator of 3/30) is greater than 22 (numerator of 2/30):

Conclusion

Therefore,

Another way to figure out which fraction is larger is to convert them into decimal numbers.

To convert a fraction to a decimal, you divide the numerator (top number) by the denominator (bottom number).

9/10 as a decimal = 9/10 = 0.9

11/15 as a decimal = 11/15 = 0.733

Since 0.9 is greater than than 0.733, 9/10 is greater than 11/15.
