Answer 2

To solve this problem, we can use the concept of equivalent fractions and cross-multiplication.

First, we need to convert the mixed numbers to improper fractions:

4 8/9 = (4 x 9 + 8)/9 = 44/9 5 5/9 = (5 x 9 + 5)/9 = 50/9

Now, we can rewrite the equation as:

44/9 = b/(5 + 5/9)

To simplify the right-hand side, we can convert 5 to an improper fraction:

5 = 45/9

Then, we can add 5/9 to get:

5 + 5/9 = 45/9 + 5/9 = 50/9

Substituting this back into the equation, we get:

44/9 = b/(50/9)

To solve for b, we can cross-multiply:

44/9 * 50/9 = b

b = 220/81

Therefore, the solution is:

4 8/9 * 1 = 220/81 / (5 5/9 * 5) = 220/2025
