The number 128 is 20 percent of 640.
A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The proportion therefore refers to a component per hundred. Per 100 is what the word percent means.
Let 128 is x percent of 640.
Here, x% of 640 =128
x/100 ×640 =128
6.4x=128
x=128/6.4
x=20%
Therefore, the number 128 is 20 percent of 640.
