1. Problem Description

The problem asks to find the missing number in the equation: "?%\text{?} \% of 50=1550 = 15". We need to determine what percentage of 50 is equal to
1
5.

2. Solution Steps

Let xx be the missing number. The problem can be written as the equation:
x100×50=15\frac{x}{100} \times 50 = 15
To solve for xx, we can multiply both sides of the equation by 100:
x×50=15×100x \times 50 = 15 \times 100
50x=150050x = 1500
Then, divide both sides by 50:
x=150050x = \frac{1500}{50}
x=30x = 30

3. Final Answer

30
