Okay, here we have this:
We need to find the least common denominator between 3/7 and 4/9:
Considering that for the denominators (7, 9), the least common multiple (LCM) is 63.
Therefore, the least common denominator (GCF) is 63.
Now let's rewrite the original inputs as equivalent fractions with the LCD:
3/7 = 3/7 × 9/9 = 27/63
4/9 = 4/9 × 7/7 = 28/63
