In the dealings with percent and percentage problems, I always tend to think of one simple rule. "Percent" means "of one hundred." This means that I am going to handle percentage problems with the concept of 100. In this case, I am moving a decimal into a percent. When moving a decimal to a percent, I will be multiplying the decimal by 100 because percent means "of 100." Another way to think of this is when I multiply of 100, I move the decimal point two places to the right because moving to the right increases (multiply) place value. This is why 0.028 as a percentage is 2.8%.

This can be expressed as 2.8%.

As you know, a percentage is how many a certain number is out of one hundred. Since 100 has two zeroes in it, that means that you need to move a decimal two places over to the right in order to change a number into a decimal.

You can also thinkgof this as multiplying the number by 100. Either way you think about it, you get the same result.

You can check this by looking at the following:

You know that .5 is equal to one half. We know that one half is 50%. So now let us move the decimal over two places. When we do, we get 50.

0.028

we need to express as a percentage:

We know that 0.028 = 28/1000

We need to find x%

x% = x/100

x/100 = 28/1000

x= 28 *100/1000= 28/10 = 2.8

Then 0.028 = 2.8 %

0.028 = 28/1000

to express it as a percent we multiply it with 100%

28/1000 * 100% = 28/10 % = 2.8%

To express 0.028 as percentage.

A pure number has no percentage. But the percentage comes in picture when a number is considered to be a ratio or compared to another number as how many time the other number it is .

If you compare 0.028 to 1, it is 0.028 times 1. Which equivalent to the the ratio: (0.028*100) compared to (1*100). Or

2.8 to 100. This we say 2.8 %

The easy working rule to convert the fraction (compared with 1 ) is shift decimal point two places left.

The number 0.028, existing as a number by itself, cannot be expressed as a percentage. Please note that in the question there is no unit defined for this number, or no other number specified. To determine a percentage we need two numbers, as a percentage is a ratio or proportion, in which the "percentage" is one part of ratio or proportion while the other part is 100.

However, if we assume 0.028 to represent a fraction, then it would imply 0.028th of 1. In this case the fraction 0.028 can be converted to percentage by multiplying it by 100. Thus

Fraction (0.028) = (0.028 x 100) percent = 2.8 percent
