Comparing Fractions

How do you compare fractions?

The first step -

Find a common denominator – by expanding and reducing or by multiplying the denominators. (Remember to multiply both the numerator and the denominator)

The second step -

Let's check which fraction is larger based on the numerators alone. The fraction with the larger numerator will be larger.

Note- First of all, we will convert whole numbers and mixed numbers to improper fractions, and only then will we find a common denominator.

Comparing fractions with identical numerators and different denominators

If the numerators are identical, the larger fraction is the one with the smaller denominator!

Comparing fractions by comparing them to 11, 12\frac{1}{2}, and 13\frac{1}{3}

Sometimes, you can compare fractions by comparing them to 11, 12\frac{1}{2}, and 13\frac{1}{3}.

How do you compare a fraction to 11?

If the numerator is larger than the denominator, the fraction is greater than 11.

If the numerator is smaller than the denominator, the fraction is smaller than 11.

In the same way, you can compare fractions to 12\frac{1}{2} and 13\frac{1}{3}!

If one fraction is greater than 12\frac{1}{2} and the other is smaller than 12\frac{1}{2}, you can determine which fraction is larger without calculating.

Exercise #2

Fill in the missing sign:

2878 \frac{2}{8}☐\frac{7}{8}

Video Solution

Step-by-Step Solution

To solve the problem, we will compare two fractions: 28\frac{2}{8} and 78\frac{7}{8}.

Both fractions have the same denominator (8), which allows us to directly compare the numerators. Therefore, we need only consider the values of the numerators to understand the relationship between the two fractions.

  • Step 1: Identify the numerators. For 28\frac{2}{8}, the numerator is 2. For 78\frac{7}{8}, the numerator is 7.
  • Step 2: Compare the numerators. We observe that 2<72 < 7.

Since 2 is less than 7, it follows that 28\frac{2}{8} is less than 78\frac{7}{8}.

Therefore, the correct sign to place between 28\frac{2}{8} and 78\frac{7}{8} is <<.

The solution to the problem is < < .

Exercise #3

Fill in the missing sign:

310110 \frac{3}{10}☐\frac{1}{10}

Video Solution

Step-by-Step Solution

To solve this problem, we need to determine which of the two fractions, 310\frac{3}{10} and 110\frac{1}{10}, is greater. Since both fractions have the same denominator, the larger fraction will be the one with the larger numerator.

We'll follow these steps:

  • Step 1: Identify the numerators of the two fractions. For 310\frac{3}{10}, the numerator is 3. For 110\frac{1}{10}, the numerator is 1.
  • Step 2: Compare the numerators. Since 3 is greater than 1, this means that 310\frac{3}{10} is greater than 110\frac{1}{10}.

Therefore, the correct mathematical sign to fill in the blank is >>.

Thus, the complete inequality is: 310>110\frac{3}{10} > \frac{1}{10}.

The correct answer is choice 2: 310>110\frac{3}{10} > \frac{1}{10}.

Exercise #4

Fill in the missing sign:

5939 \frac{5}{9}☐\frac{3}{9}

Video Solution

Step-by-Step Solution

To compare fractions with the same denominator, focus on the numerators:

  • Given fractions: 59\frac{5}{9} and 39\frac{3}{9}
  • Since both fractions have the same denominator (9), we only need to compare the numerators.
  • Numerator of the first fraction is 5, and the numerator of the second fraction is 3.
  • Since 5 is greater than 3, 59\frac{5}{9} is greater than 39\frac{3}{9}.

Therefore, the missing sign that correctly compares the two fractions is >>, so the correct statement is:

59>39\frac{5}{9} > \frac{3}{9}.
