Steps to solve:

1/3 b = 4/5

(3/1) * (1/3 b) = (4/5) * (3/1)

b = 12 / 5

b = 2 2/5

The correct answer is the first option, 2 2/5.

Hope this helps!! :)

Answer:

2 2/5

Step-by-step explanation:

b/3 = 4/5

We can solve using cross products

5b = 3*4

5b = 12

Divide each side by 5

5b/5 = 12/5

b = 12/5

b = 2 2/5
