Step 2: Use the variable 'x' to represent the unknown value.
Step 3: From Step 1, we know that 18 is equivalent to 100%.
Step 4: Similarly, we can determine that 'x' represents 40% of the value.
Step 5: This leads us to two simple equations:
Step 6: To solve for 'x', we divide equation 1 by equation 2, considering that both equations have the same unit (%). Thus, we obtain:
45 / x = 100% / 40%
Step 7: By taking the reciprocal of both sides of the equation obtained in Step 6, we have:
x / 45 = 40 / 100
⇒ x = 18
Therefore, we conclude that 40% of 45 is equal to 18.
