To find the total amount based on the information that 125% equals 85 cm, you can set up a simple equation.
Let \( x \) be the whole (100%). We know that:
\[ 125% = 1.25x \]
According to the information given:
\[ 1.25x = 85 \text{ cm} \]
Now, to find \( x \), we can rearrange the equation:
\[ x = \frac{85}{1.25} \]
Now, calculate \( x \):
\[ x = \frac{85}{1.25} = 68 \text{ cm} \]
So, 100% (the whole amount) is 68 cm.
To find other specific percentages, you can multiply 68 cm by different percentage values (like 50%, 75%, etc.) as needed.
