# How to present fractions of a percent to a layman

• 2milehi
In summary, the conversation centers around presenting data that includes fractions of a percent and finding a way to convey how small these numbers are to a layman. Ideas such as using food analogies and breaking down the numbers into smaller units are suggested. It is also acknowledged that the issue may not be with understanding percentages, but with the presentation of the data itself.

I have been presenting some data and I was asked to present it "better". The figures have been fractions of a percent (e.g. 0.05%) and I would like to convey how small that is to a layman. I don't want to go to Parts Per Million and my first thought is to say 1/20th of 1% represents 0.05%.

Any ideas out there?

I dunno.. 5 cents per hundred ?

Is that what you meant?

Dollars are always implied. We're talking business, son : )

By "layman" I guess you mean someone who doesn't understand 6th grade arithmetic. "percent" means literally, "per 100" so .05% means (5/100) x (1/100) or (1/20) x (1/100) = 1/2000.

Other ways to say this are 1/2 part in 1,000 or 5 parts in 10,000.

Are you sure the problem was that your audience didn't understand percentages and that it wasn't because you were simply presenting poorly? e.g. jumping all over the place, having trailing thoughts, being too succinct in some parts and delving too deeply in others, etc.

To the layman, you say? All men understand food, so choose that food analogy: the pie chart and you can't go wrong.

... "If you take this tiny (1° slice) and share it among 6 people, then each will get about 0.05% of the pie."

I was presenting data in a table via an email and that was all, no interpretation. My boss made a mistake by trying to understand how small 0.05% is. When he was working "backwards" from 40 minutes out of ~80,000 minutes, he would up with 0.005% or 4 minutes. That is when he asked me if there was another way to present a small fraction of a percent.

How about three quarters of a minute, over a whole day? (actually it's 43.2 s, not 45 s; but maybe that's close enough?)

## 1. What is the best way to present fractions of a percent to a layman?

It is best to present fractions of a percent in a clear and simple manner. This can be done by using visual aids such as graphs or charts, or by providing real-life examples that can help the layman understand the concept better.

## 2. How do I convert a fraction of a percent to a decimal or a whole number?

To convert a fraction of a percent to a decimal, simply divide the numerator (top number) by the denominator (bottom number) and move the decimal point two places to the left. To convert to a whole number, multiply the decimal by 100 and remove the decimal point.

## 3. Is it necessary to use mathematical symbols when presenting fractions of a percent?

No, it is not necessary to use mathematical symbols when presenting fractions of a percent. In fact, it may be easier for a layman to understand if the fraction is written out in words, such as "one-third of a percent" instead of "1/3%".

## 4. How can I make fractions of a percent more relatable to a layman?

One way to make fractions of a percent more relatable is by using real-life examples. For instance, you could say "2 out of every 10 people" instead of "20%". This helps the layman understand the fraction in terms of something they can visualize.

## 5. Are there any common misconceptions about fractions of a percent that I should address?

One common misconception is that fractions of a percent are insignificant or negligible. However, even small fractions of a percent can have a significant impact, especially in fields such as finance and healthcare. It is important to highlight the significance of these fractions when presenting them to a layman.
