Compare 12/15 and 7/10

Comparing fractions like 12/15 and 7/10 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 15 and 10. The smallest common multiple of 15 and 10 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 12/15 to a fraction with a denominator of 30, multiply both the numerator (top number) and the denominator by 2. This gives:

To convert our second fraction 7/10 to a fraction with a denominator of 30, multiply both the numerator and the denominator by 3. This gives:

Step 3: Compare the Numerators

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

The numerators are 24 for 24/30 and 21 for 21/30.

Step 4: Determine the Larger Fraction

The fraction with the larger numerator is the greater fraction.

Since 24 (numerator of 2/30) is greater than 21 (numerator of 3/30):

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).

12/15 as a decimal = 12/15 = 0.8

7/10 as a decimal = 7/10 = 0.7

Since 0.8 is greater than than 0.7, 12/15 is greater than 7/10.
