If 25 is 40% of a value, what is that value?
luda_lava [24]
The value is 62.50

To the get whole value or 100 % of the value, we always divide the value to its corresponding percentage.

25 is the value; 40% is the percentage of 25 from the whole value.

25 / 40% = 62.50

In the event that the value of a part and the whole is given and the percentage is required. Simply divide the part by the whole to get its percentage of the whole.

whole = 62.50
part = 25

25 / 62.50 = 0.40 * 100% = 40%

If the whole value and the percentage is given. To find the value of the percentage, simply multiply the whole to the percentage.

whole = 62.50
percentage = 40%

62.50 * 40% = 25
