Solution Steps

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 64 percent of 128. What are the steps?

Step 1: first determine the value of the whole amount. We assume that the whole amount is 128.

Step 2: determine the percentage, which is 64.

Step 3: Convert the percentage 64% to its decimal form by dividing 64 into 100 to get the decimal number 0.64:

64100 = 0.64

Notice that dividing into 100 is the same as moving the decimal point two places to the left.

64.0 → 6.40 → 0.64

Step 4: Finally, find the portion by multiplying the decimal form, found in the previous step, by the whole amount:

0.64 x 128 = 81.92 (answer).

The steps above are expressed by the formula:

P = W × X%100

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 = 128 × 64100 = 128 × 0.64 = 81.92 (answer)

Therefore, the answer is 81.92 is 64 percent of 128.

Solution for '64 is what percent of 128?'

The following question is of the type "P is what percent of W,” where W is the whole amount and P is the portion amount".

The following problem is of the type "calculating the percentage from a whole knowing the part".

Solution Steps

As in the previous example, here are the step-by-step solution:

Step 1: first determine the value of the whole amount. We assume that it is 128.

(notice that this corresponds to 100%).

Step 2: Remember that we are looking for the percentage 'percentage'.

To solve this question, use the following formula:

X% = 100 × PW

This formula says that:

"To find the percentage from the whole, knowing the part, divide the part by the whole then multiply the result by 100".

This formula is the same as the previous one shown in a different way in order to have percent (%) at left.

Step 3: replacing the values into the formula, we get:

X% = 100 × 64128

X% = 6400128

X% = 50.00 (answer)

So, the answer is 64 is 50.00 percent of 128

Solution for '128 is 64 percent of what?'

The following problem is of the type "calculating the whole knowing the part and the percentage".

Solution Steps:

Step 1: first determine the value of the part. We assume that the part is 128.

Step 2: identify the percent, which is 64.

Step 3: use the formula below:

W = 100 × PX%

This formula says that:

"To find the whole, divide the part by the percentage then multiply the result by 100".

This formula is the same as the above rearranged to show the whole at left.

Step 4: plug the values into the formula to get:

W = 100 × 12864

W = 100 × 2

W = 200 (answer)

The answer, in plain words, is: 128 is 64% of 200.
