Given that a/4 = b/7, we can rewrite this equation as:
a = 4b/7
Now, we want to find the value of (a-b) / b. We substitute the value of a from the above equation into the expression:
(a-b) / b = (4b/7 - b) / b
= (4b - 7b) / 7b
= -3b / 7b
= -3/7
Therefore, the value of (a-b) / b is -3/7.
If a/4 = b/7, what is the value of (a-b) / b?
