How do you convert 42 percent into a whole number?

The smallest whole number is ' 1 '. 42% is another way to write the number 0.42 and that's less than ' 1 ' . So 42 percent doesn't have what it takes to be a whole number, no matter what you do to it.

What is 18 percent as a whole number?

If every percent could be converted to a whole number, we wouldn't need percent. The smallest whole number is ' 1 '. If you cut up a ' 1 ' into five pieces, 18 percent is smaller than one of the pieces. 18 percent doesn't have what it takes to be even the smallest whole number. There's no way to change 18 percent to a whole number.

A can complete a piece of work in 12 days and B is 60 percent efficient than A. In how many days B will complete the same work..?

What is 0.5 percent as a mixed number in simplest form?

0 and 1/200 A "mixed number" is a whole number plus a fraction. So every mixed number must be bigger than ' 1 '. 0.5 percent = 0.005, which is quite a bit smaller than ' 1 '. So 0.5 percent just doesn't have what it takes to be a mixed number.

What is 0.001 percent?

It is one thousandth of one percent. In other words, it takes one thousand of those units to make one percent of the whole quantity.It is strange when you start combining small decimal fractions with the word percent. It might help to think of it this way. "percent" always means one hundredth, 1/100. Whatever number comes before "percent" has to be multiplied by 1/100. Five percent, or 5 percent or 5% means 5 hundredths. One tenth of a percent, or 0.1 percent, means it takes 10 of these to equal ONE PERCENT. The number 0.001 without the word percent means simply one thousandth of the whole quantity; it doesn't mean one thousandth of a percent. So 0.001 is equal to 0.1 percent; one thousandth is the same as saying one tenth of one percent.

What is the difference between atomic percent and weight percent?

Atomic percent is based on the number of atoms in a sample. So if the sample has x number of oxygen atoms and x number of iron atoms it would report 50% oxygen and 50% iron (atomic percent). Weight percent is based on the mass of the elements detected. So if we used the above example and reported the results as weight percent we would get 22.3% oxygen and 77.7% iron. Weight percent takes into consideration the mass or atomic weight of the elements and not just the number of atoms. Most people use weight percent although for chemistry atomic percent may be more useful.
