Step-by-Step Solution

To solve this problem, we'll perform the following steps:

  • Step 1: Find the Least Common Denominator (LCD) of 33 and 99.
  • Step 2: Convert each fraction to have the LCD as its denominator.
  • Step 3: Subtract the numerators of the converted fractions.
  • Step 4: Simplify the resulting fraction if needed.

Let's proceed with the steps:

Step 1: The denominators of the given fractions are 33 and 99. The LCD of 33 and 99 is 99 since 99 is the smallest multiple that both 33 and 99 divide into evenly.

Step 2: Convert each fraction to have a denominator of 99.

23 \frac{2}{3} can be converted to an equivalent fraction with the denominator 99 by multiplying the numerator and denominator by 3:

23×33=69 \frac{2}{3} \times \frac{3}{3} = \frac{6}{9}

The second fraction 49 \frac{4}{9} already has the denominator 99, so it remains unchanged.

Step 3: Subtract the fractions: 6949 \frac{6}{9} - \frac{4}{9} .

Since the denominators are now the same, subtract the numerators:

64=2 6 - 4 = 2

The resulting fraction is 29 \frac{2}{9} .

Step 4: Check if there is a need to simplify. The fraction 29 \frac{2}{9} is already in its simplest form.

Thus, the solution to the problem is 29 \frac{2}{9} .

Answer

29 \frac{2}{9}
