Problem:
If a/b= 2, what is the value of 4b/a?
A) 0
B) 1
C) 2
D) 4
Hint:
Start by substituting the value of a (which is given by a/b into 4b/a) to solve for the value directly.

Use substitution to solve for the required expression. Make sure you plug in the value of 'a' correctly.”

Example:
Let's say you're given: a/b = 3 Which implies: a = 3b To find : 5b/a, substitute for a: 5b/3b = 5/3

Given c/d = 3 , which means c = 3d.
If we need to find 2d/c, we would substitute c = 3d into the expression:
2d/c = 2d/3d
This reduces to:
