Steps to Solve
- Set up the equation
To find the percentage ( x ) of 68 that equals 51, we can set up the equation: $$ \frac{x}{100} \times 68 = 51 $$

- Calculate the right side
Now calculate the multiplication on the right side: $$ x \times 68 = 5100 $$
- Solve for ( x )
Next, divide both sides by 68 to isolate ( x ): $$ x = \frac{5100}{68} $$
