What does it mean to compare fractions?

Back

Comparing fractions means determining which fraction is larger, smaller, or if they are equal. This can be done using models, common denominators, or cross-multiplication.

How do you compare fractions with the same denominator?

Back

When fractions have the same denominator, you can compare them by looking at their numerators. The fraction with the larger numerator is the larger fraction.

How do you compare fractions with different denominators?

Back

To compare fractions with different denominators, you can find a common denominator or convert them to decimals. Alternatively, you can use cross-multiplication.

Front

What is a common denominator?

Back

A common denominator is a shared multiple of the denominators of two or more fractions. It allows you to compare or add fractions easily.

Front

What is cross-multiplication?

Back

Cross-multiplication is a method used to compare two fractions. You multiply the numerator of the first fraction by the denominator of the second fraction and vice versa. If the products are equal, the fractions are equal.

How can models help in comparing fractions?

Back

Models, such as pie charts or bar models, visually represent fractions, making it easier to see which fraction is larger or smaller by comparing the sizes of the parts.

Front

What is the first step in comparing fractions?

Back

The first step in comparing fractions is to determine if they have the same denominator. If they do, compare the numerators. If not, find a common denominator.
