Calculate the whole if 64 percent is equal to 5:

To solve this problem, we'll follow these steps:

• Step 1: Convert the given percentage to a decimal.
• Step 2: Use the formula to solve for the whole.
• Step 3: Calculate and identify the correct option.

Now, let's work through each step:
Step 1: The given percentage is 64%. To convert it to a decimal, we divide by 100: $64\% = 0.64$.

Step 2: Use the formula for finding the whole:
$\text{Whole} = \frac{\text{Part}}{\text{Percentage as a decimal}} = \frac{5}{0.64}$

Step 3: Perform the division:
$\frac{5}{0.64} = 7.8125$

Therefore, rounding to two decimal places, the whole is $7.81$.
