65 percent of 40?
Solution for 'What is 65% of 40?'
In the following example consider that:
- The percentage figure is represented by X%
- The whole amount is represented by W
- The portion amount or part is represented by P
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 65 percent of 40. What are the steps?
Step 1: first determine the value of the whole amount. We assume that the whole amount is 40.
Step 2: determine the percentage, which is 65.
Step 3: Convert the percentage 65% to its decimal form by dividing 65 into 100 to get the decimal number 0.65:
65 = 0.65
Notice that dividing into 100 is the same as moving the decimal point two places to the left.
65.0 → 6.50 → 0.65
Step 4: Finally, find the portion by multiplying the decimal form, found in the previous step, by the whole amount:
0.65 x 40 = 26 (answer).
The steps above are expressed by the formula:
P = W × X%
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 = 40 × 65 = 40 × 0.65 = 26 (answer)
Therefore, the answer is 26 is 65 percent of 40.
