Enlarge the Fraction 7/9 by a Factor of 9: Step-by-Step Solution

Enlarge the following fraction by the factor 9:

$\frac{7}{9}=$

To solve this problem, we need to enlarge the fraction $\frac{7}{9}$ by a factor of 9.

First, let's restate the initial fraction:

• The given fraction is $\frac{7}{9}$.
• The factor to enlarge by is 9.

Now, we'll apply the enlargement:

• Multiply the numerator (7) by the factor 9:
  $7 \times 9 = 63$.
• Multiply the denominator (9) by the factor 9:
  $9 \times 9 = 81$.

Thus, the enlarged fraction is $\frac{63}{81}$.

Comparing this result with the given multiple choice options confirms that our answer is option 3, $\frac{63}{81}$.

Therefore, the enlarged fraction is $\frac{63}{81}$.
