How do you compare fractions with different denominators?

We can compare fractions with unlike denominators by finding the least common denominator, or the smallest multiple the denominators share. Then we make equivalent fractions, or fractions that represent the same part of the whole.

How do you compare fractions with different numerator and denominator?

How to Compare Fractions with Different Denominators? In order to compare fractions with different denominators, we need to find the Least Common Multiple (LCM) of the denominators and convert the given fractions to like fractions by making their denominators the same and then the numerators can be easily compared.

What are 4 ways to compare fractions?

This part explores four strategies for comparing fractions (Van de Walle et al., 2009): More of the same-size parts (common denominator) Same number of parts, but parts of different sizes (common numerator) More and less than a benchmark such as one-half or one whole.

How do you match denominators?

To make the denominators the same we can: Multiply top and bottom of each fraction by the denominator of the other.

Why do we compare fractions?

It is important for students to begin comparing fractions with a concrete representation, such as the area model to help them understand the size of the parts and number of parts. Using representations to compare fractions help students develop their number sense about fraction size.

Comparing Fractions With Different Denominators

How do you compare fractions for kids?

When comparing fractions, you use the 'less than', 'greater (bigger) than', and 'equal to' signs. See picture B. 5. So, going back to the chocolate example, you'll write the 'less than' sign in the middle since 1/2 is less than 3/5.

What are 3 ways to compare fractions?

What if the denominator is different?

Adding Fractions: If the denominators are not the same, you must find the common denominator by finding the least common multiple (LCM). Subtracting Fractions: If the denominators are not the same, you must find the common denominator by finding the least common multiple (LCM).

How do you compare fractions that are bigger?

Compare fractions: If denominators are the same you can compare the numerators. The fraction with the bigger numerator is the larger fraction.

Why do denominators have to be the same?

If you're adding two fractions with a common denominator, you can combine them together by adding the numerators together (the top numbers). The denominator will always stay the same because the size of the equal pieces does not change when you combine the two fractions together.

What do you call fractions with different denominators?

Unlike fractions are defined as those fractions which have different denominators.

What are the rules of fractions?

To add or subtract fractions they must have the same denominator (the bottom value). If the denominators are already the same then it is just a matter of either adding or subtracting the numerators (the top value). If the denominators are different then a common denominator needs to be found.
