Compare 10/12 and 10/15

Comparing fractions like 10/12 and 10/15 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 12 and 15. The smallest common multiple of 12 and 15 is 60. Therefore, 60 will be our common denominator.

Step 2: Convert the Fractions

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

To convert 10/12 to a fraction with a denominator of 60, multiply both the numerator (top number) and the denominator by 5. This gives:

To convert our second fraction 10/15 to a fraction with a denominator of 60, multiply both the numerator and the denominator by 4. This gives:

Step 3: Compare the Numerators

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

The numerators are 50 for 50/60 and 40 for 40/60.

Step 4: Determine the Larger Fraction

The fraction with the larger numerator is the greater fraction.

Since 50 (numerator of 5/60) is greater than 40 (numerator of 4/60):

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).

10/12 as a decimal = 10/12 = 0.833

10/15 as a decimal = 10/15 = 0.667

Since 0.833 is greater than than 0.667, 10/12 is greater than 10/15.
