### What is a mixed number or in a fraction in simplest form 0.15%

A mixed number is a number composed of an integer (whole) number and a proper fraction, one that has a numerator less than the denominator. Example 2 1/3 =2+ 1/3. 2 is the integer part, and 1/3 is the proper fraction part.
Certain fractions can be simplified further because the numerator and denominator share a (common) factor. By cancelling the common factor in the numerator with the factor in the denominator,
one gets a fraction with smaller numerator and denominator.
For example the percentage you provide 0.15% can be converted to 15/10000.
Since 15 and 1000 are both multiples of 5, the number 5 is a common factor in both. 15=5*3, and 10000=5*2000
Cancel the two 5 (simplifying by 5) in numerator and denominator leaves 3/2000. Thus
0.15%= 0.15/100=0.0015=3/200
I hope that this makes sense to you.

### How do I convert decimals to fractions on the TI Math Explorer (No numbers associated with it - i.e. TI - 15)?

The way it works is as follow. If a result is displayed as a fraction you can convert it to its decimal representation. If you do nothing after the conversion, you can revert the decimal representation to the fraction.

### What does the numerator of a fraction tell you

By itself, nothing. There are an infinite number of fractions with the same numerator, and any fractional number can have an infinite number of representations, each with a different numerator.

For example, consider the numerator "2". The fraction could be 2/3, 2/4, 2/5, 2/6, 2/7, etc.

Now consider the fraction "2/3". It can also be written as 4/6, 6/9, 8/12, 10/15, 12/18, etc.

### How many tenths there are in 11/2?

Just convert the 1 and 1/2 to a fraction and then multiply the top and bottom (numerator and denominator) by 5 to see that fraction in tenths.

Multiplying both the numerator and the demominator of a fraction by the same number does not change the value of the fraction.

1 1/2 is the same as 3 / 2

Now multiply both top and bottom by 5.

3 / 2 = 15 / 10

Therefore there are 15 tenths in 1 1/2.

Good luck I hope this helps.

Joe.

### I don't know how to simplify fractions on this calculator.

You do not simplify fractions on the calculator. If the calculator is able to display fraction results, be sure that the form it gives you is the simplest. If the fraction is a mixed one there is usually a key to switch from mixed to improper, and from improper to mixed the keys are [a b/c] and [d/c]

To convert decimals into fractions in a TI-15 calculator you should do the following:

1) Enter the decimal number you wish to convert, for example: 0.075 and press ENTER.

2) Press the F<-->D button

It also works the other way around. There is a great Power Point presentation that resumes the basic operations of this particular calculator at NING published by EMRTs

### Fractions

I checked the manual for the EL-501W calculator and I found out that it does not do fraction calculations. However yours may be able to. Look for a key labeled [a b/c] and a [2ndF] key [d/c].

If you have them then you can calculate with fractions.

The way to use the [a b/c] key is as follows
15 [a b/c] 7 [a b/c] 19 [a b/c] should allow you to enter 15 and 7/19.
A mixed fraction can be converted into an improper fraction by pressing [2ndF][d/c]
