Ratio and Proportion: 450:15=225: X
X=7.5
X=30
X=15
X=60
Correct Answer : A
Set up the proportion as fractions:
= 
First, simplify the left side ratio:
= 30
This means for every 15 units on the left, there are 450 units. To maintain this proportion, the ratio on the right must behave similarly:
30 =
Now, solve for 𝑋X by cross-multiplying:
30⋅𝑋=225
Simplify to find X:
𝑋= 
= 7.5
This correct calculation verifies that 𝑋=7.5, matching the proportion given.
Thus, the answer is A. X = 7.5.

To convert the decimal 0.16 to a fraction, follow these steps:
- Write it as a fraction of 1:
0.16= 
- Multiply both the numerator and the denominator by 100 to eliminate the decimal places (because there are two decimal places in 0.16):
=
- Simplify the fraction by finding the greatest common divisor (GCD) of the numerator and the denominator: The GCD of 16 and 100 is 4, so divide both the numerator and the denominator by 4:
= 
The correct fraction representation of 0.16 is therefore .
So the answer is B 4/25.

=
Now, we cross multiply:
125×𝑋=5×75
125𝑋=375
Now, solve for X by dividing both sides by 125:
𝑋 =
= 3
So, the value of X is 3.
Therefore, the correct answer is: C X= 3
