How to find the percentage of whole numbers
The Shortcut Method
The method relies on converting the percentage to a fraction, but the multiplication step is simplified.
 
Let’s use the example: What is 300% of 52?
Step 1: Convert the Percentage to a Fraction
30% = 300/100
Step 2: Use Simplified Multiplication to multiply the numerator.
The multiplication is 300 × 52. Since both numbers end in zero, you can use a trick:

1. Ignore the Zeros: Multiply the non-zero digits:
   3 × 52 = 156
   
2. Add the zeros to the end of the number.
   15 → 15600
   Step 3: Divide by the denominator.
   Divide by 100 by moving the decimal 2 places to the left.
   15600 → 156
   So, 300% of 52 = 156.
