When you wish to compare is to another number.
Since 50% of 16 is 8 we can estimate that 52 percent of 16 would be slightly higher than 8, or 8.1-8.4.
52% of 38 = 0.52 * 38 = 19.76 which when estimated to the nearest whole number = 20.
first you would have to estimate the division problem once you do that just move your decimal 2 spaces to the right for example if you have four eighths you would round four to five and eight to ten and then you divide
I would estimate 29.
Multiply the number by the percent in decimal form. Example: 10 percent of 200 would be 200 x .10 = 20. (10 per cent of 200 is 20.)
i would say they way to get the ballpark estimate is by taking the number. and see what is the estimate for that number and then you take that estimated number and then add to get your answer .
26.2% would be first.
Expressed as a decimal number, 82.45 percent is equal to 0.8245.
An estimate, which can be obtained quickly, can sometimes be sufficient for the immediate purpose. It may be better than an exact answer which will take time.
To convert a number into a percent you multiply the number and add a percent symbol. So 1.562 would be 156.2%
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.
