The following question is of the type "How much X percent of W", where W is the whole amount and X is the percentage figure or rate".
Let's say that you need to find 2.85 percent of 3.8. What are the steps?
Step 1: First determine the value of the whole amount. We assume that the whole amount is 3.8.
Step 2: Determine the percentage, which is 2.85.
Step 3: Convert the percentage 2.85% to its decimal form by dividing 2.85 by 100 to get the decimal number 0.0285:
2.85100 = 0.0285
Notice that dividing by 100 is the same as moving the decimal point two places to the left.

Step 4: Finally, find the portion by multiplying the decimal form found in the previous step by the whole amount:
0.0285 x 3.8 = 0.1083 (answer).
The steps above are expressed by the formula:

This formula says that:
"To find the portion or the part from the whole amount, multiply the whole by the percentage, then divide the result by 100".
The symbol % means the percentage expressed in a fraction or multiple of one hundred.
Replacing these values in the formula, we get:
P = 3.8 × 2.85100 = 3.8 × 0.0285 = 0.1083 (answer)
Therefore, the answer is 0.1083 is that 2.85 percent of 3.8.
