Multiply Fraction 3/7 by a Factor of 3: Step-by-Step Solution

To solve this problem, we'll follow these steps:

• Step 1: Identify the original fraction, which is $\frac{3}{7}$.
• Step 2: Multiply both the numerator and denominator by 3 to increase the fraction by a factor of 3.
• Step 3: Calculate the new fraction.

Now, let's work through each step:
Step 1: The original fraction is $\frac{3}{7}$.
Step 2: Multiply the numerator (3) by 3 to get 9, and multiply the denominator (7) by 3 to get 21.
So, the new fraction becomes $\frac{9}{21}$.

Therefore, the solution to the problem is $\frac{9}{21}$.
