2. Cross-multiply: To solve for x, we cross-multiply: 70 * 100 = 280 * x This simplifies to 7000 = 280x

3. Isolate x: To find the value of x, we divide both sides of the equation by 280: 7000 / 280 = x

4. Calculate the result: 7000 divided by 280 equals 25. Therefore, x = 25.

5. Express as a percentage: This means that 70 is 25% of 280.

Alternative Method: Using Decimal Calculation

Another approach involves converting the fraction to a decimal first:

1. Divide 70 by 280: 70 / 280 = 0.25
