You do the operation to get a decimal number.

Isolate the integer part (to the left of the decimal point)

Convert the non integer part (decimal part) into a fraction.

Write the result as (integer part) (fraction part)

3/2=1.5

Integer part is 1, decimal part is 0.5

0.5 as a fraction is 1/2

3/2= 1 1/2

Isolate the integer part (to the left of the decimal point)

Convert the non integer part (decimal part) into a fraction.

Write the result as (integer part) (fraction part)

3/2=1.5

Integer part is 1, decimal part is 0.5

0.5 as a fraction is 1/2

3/2= 1 1/2

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.

By hand you can write every integer you wish as a fraction with denominator 1. 4=4/1, 13=13/1. You can even generate all the equivalent fractions of any integer, for example -4=(-8/2)=8/(-2)=-8/2=-12/3=...

However, simple calculators are designed with a feature called automatic simplification. That is why ever result that is a fraction that is equivalent to an integer is written as that integer. Fractions are reduced to their simplest form.** Call it a design flaw if you want but that is how it is.**

Finding the remainder from a division calculation is often referred to as using the MOD function, though this isn't available directly on the fx-991ES.

To obtain the remainder, for example when dividing 10 by 7, you can only divide 7 into 10 once, leaving a remainder of 3.

For larger numbers, eg when dividing 389487 by 31 (equivalent to 389487MOD31) the division gives an answer of 12564.09677 (on the display), however you only want the fractional part so subtract 12564 to give 0.0967741935 . This includes the lower value digits that were previously hidden. Then multiply this result by 31 which gives 2.999999999 on the display. Since the result of a MOD or remainder calculation involving integers has to be a whole number, the answer needs to be rounded to 3. If the answer doesn't easily round to a whole number, it is likely that you have gone beyond the calculator's working capacity.

An alternative method which avoids the rounding of the fractional part is to take the integer part of the first result (12564) and multiply it by 31 to get 389484, then subtract this from 389487, giving the answer of 3.

I am sorry but the question does not make sense. The millimeter is a unit of length (physical unit), while a fraction is a mathematical object that is defined as the ratio of two integers. It involves dividing two integer (whole) numbers, such as 1/3.

Would you care to reformulate the question?

hi maybe the formula below will help you

A rational number is a number that can be expressed as a fraction with an integer numerator and a non-zero natural number denominator. Fractions are written as two numbers, the numerator and the denominator, with a dividing bar between them. In the fraction written*m*⁄*n* or

*m* represents equal parts, where *n* equal parts of that size make up one whole. Two different fractions may correspond to the same rational number; for example 1⁄2 and 2⁄4 are equal, that is:

If the absolute value of*m* is greater than *n*, then the absolute value of the fraction is greater than 1. Fractions can be greater than, less than, or equal to 1 and can also be positive, negative, or zero. The set of all rational numbers includes the integers, since every integer can be written as a fraction with denominator 1. For example −7 can be written −7⁄1. The symbol for the rational numbers is **Q** (for *quotient*), also written .

Hello,

There is no fraction button, but if you divide two integers (whole numbers) and want to keep the result as a fraction press [MATH][1:|=>Frac] [ENTER]. If the fraction can be reduced to its simplest form that is the result you will have.

27/48 [MATH][1:|=>Frac][ENTER] displays 9/16

Hope it helps.

Hello,

To convert fractions to decimals or decimals to fractions, you use the [S<->D] key. Each time you press the key the result is displayed in the other format.

Alternatively, If you multiply or divide two integer numbers put a decimal mark at the end of one of the numbers (any one). The result will be displayed in decimal format.

Hope it helps.

Proper fraction e.g. 3/5, input 3, divide, 5, =, answer 0.6

Improper fraction, either enter as improper fraction, or enter the whole number first, then +, then the proper fraction as before, then =.

E.g. 8/5 which is "1 and 3/5': enter 1, +, 3, "divide", 5 =, answer is 1.6

Or, just 8, "divide", 5, same 1.6 answer. Why go to mixed number first?

13/5 which is "2 and 3/5", enter 2, +, 3, "divide", 5, =, answer is 2.6. Or, just 13/5, same answer
