the movement of the progress bar may be uneven because questions can be worth more or less (including zero) depending on your answer. change $2\frac{7}{9}$ from a mixed number to an improper fraction. \\(\frac{25}{9}\\) \\(\frac{21}{9}\\) \\(\frac{23}{9}\\) \\(\frac{9}{25}\\)

Explanation:

Step1: Recall the formula for converting a mixed number \( a\frac{b}{c} \) to an improper fraction: \( \frac{a\times c + b}{c} \)

For the mixed number \( 2\frac{7}{9} \), \( a = 2 \), \( b = 7 \), \( c = 9 \)

Step2: Calculate the numerator

Multiply the whole number part by the denominator: \( 2\times9 = 18 \)
Then add the numerator: \( 18 + 7 = 25 \)
The denominator remains \( 9 \)
So the improper fraction is \( \frac{25}{9} \)

Answer:

A. \(\frac{25}{9}\)
