The number for which 85 is 20% of it is $425$.
Steps to Solve
- Set up the percentage equation
We can express the given information using the formula for percentages, which is:
$$ \text{Percentage} = \frac{\text{Part}}{\text{Whole}} \times 100 $$
In this case, we know that 85 is 20% of some number (let's call it $x$). So we can set up the equation as:
$$ 20 = \frac{85}{x} \times 100 $$
- Simplify the equation
To simplify, we can multiply both sides by $x$ to eliminate the fraction:
$$ 20x = 85 \times 100 $$
This gives us:
$$ 20x = 8500 $$
- Solve for $x$
Now, we can isolate $x$ by dividing both sides by 20:
$$ x = \frac{8500}{20} $$
- Calculate the value of $x$
Performing the division:
$$ x = 425 $$
The number for which 85 is 20% of it is $425$.
More Information
