I need help with improper fractions may you please help me thanks

I think you want to reduce the fraction to the lowest terms.

Improper fraction 1 3/4 produces an improper fraction of 7/4 (1 times denominator plus numerator)

To reduce a fraction, we need to divide the numerator (number on top) and the denominator (number on the bottom) by the greatest common factor (GCF).

To get the GCF, find the factors of the numerators and denominators and find the greatest number that is in both lists.

The factors of 2 are 1, 2.

The factors of 10 are 1, 2, 5, 10.

The greatest (largest) number is both lists is 2, so we divide the numerator and denominator by 2 and get 1/5.

Good luck,

Paul

I think of pizzas when doing fractions. If you cut the four full pizzas into thirds, how many slices will you have? Add this to the two other slices and you get your improper fraction.

So, to make an improper fraction, you multiply the whole number by the denominator and add it to the numerator. To get more improper fractions, you can multiply the numerator and denominator by the same number.

improper. In a proper fraction, the numerator must be less than the denominator. If it is not the case then it is an improper fraction.
9/2=4 1/2

Convert each mixed number (what you call mixed fraction) to an improper fraction, then multiply the two numerators and multiply the two denominators. Reduce the resulting fraction to its simplest form

Example
(2 1/3)*(1 5/7)=?
Convert 2 1/3 to an improper fraction 2 1/3=2+ 1/3 = 6/3+1/3=7/3
Convert 1 5/7 to an improper fraction 1 5/7=1+ 5/7 =7/7 +5/7=12/7
(2 1/3)*(1 5/7)= (7/3)*(12/7)= (7*12)/(3*7)
The 7's in the numerator and denominator cancel one another leaving
12/3=4
(2 1/3)*(1 5/7)=4
Not all products of mixed numbers will give a simple result as this one. More likely they will not.

A proper fraction is one where the numerator is less than the denominator 1/3, 2/3,1/4, 5/9. All these values are less than 1.
Take now the fraction 17/8. This is not a proper fraction because the numerator is NOT less the denominator. The result can be written as a mixed number (2 1/8) or an improper fraction (17/8)

The Improper fraction of 6 2/5 is 32/5. I would like to know or clarify the concern about the 30x?

Hi eamon at hom,

Doing fraction on the Sharp El 531W really isn't that bad. I had to use pictures because, the symbols will not transfer over to your posting for me to show you. When you select the [ON/C] this clears the calculator of previous calculations and, data so that they won't interfere with your new calculations.

Let take the first example where a mix number is being added to a improper fraction. Because I used the [a^b/c] key this makes the calculator display the answer in a mixed fraction format or, a proper fraction format. If I press the [a^b/c] key again after the answer the format will change to a decimal format. The fractional formats are displayed in a mixed number, improper or, proper fraction formats. A improper fraction is really a proper fraction number with the top number (numerator) is greater than or equal to the bottom number (denominator).

[ON/C] [3] [a^b/c] [1] [ [a^b/c] [2] [+] [4] [a^b/c] [3] [=] mixed number results. Now let's do the same calculation as a improper or, proper fraction format.
[ON/C] [7] [a^b/c] [2] [+] [2] [a^b/c] [3] [=] still a mixed number result. Even though I enter the fractions in a improper and, proper fraction formats the calculator will still display in a mixed number format. This is because the calculator first displays as a mixed number if it can. If it can't then it will display the value as a proper fraction and, never as a improper fraction. To convert from a mixed number to a improper fraction format if the calculator did not convert it to a proper fraction, I have to use [2ndF] [d/c] keys on the command line.



This show a little more complex raised power use of the [a^b/c] key.

This shows the [2ndf] [x^-1] keys being used to calculate fractions.


When I first saw this question being asked it, was answered with just use the / command. Which that isn't really a good answer because, in math we like to use elimination. If you use the / command eventually the numbers are going to be rounded off and, your not going to be able to eliminate anything. If you have any further question on how to preform fractions with this calculator be sure to post your comment and, I'll be glad to help.

Enters a proper or improper fraction,
b?c (b { 6 digits, c { 3 digits). When
possible, improper fractions are
displayed as mixed numbers.
3 F 4 3?4
8 3 J 21?4
Single-variable functions display
decimal results.
1 F 2 0 0.25
a F b F c Enters the mixed fraction a b?c.
(a, b, c { 3 digits each, with the total
digits { 8).
6 F 4 F 6 64?6
J 62?3
"s Toggles display between a mixed
number and an improper fraction.
30 F 4 30?4
"s 71?2
"s 15?2
"s 71?2
"y Toggles display between fraction and
decimal.
55 F 24 55?24
"y 2.291666667
"y 27?24
If a result would overflow or if fixed decimal is 0, no
fraction to decimal conversion occurs. It is not an error.
Denominator must be a whole number {999.

Hello

10[ab/c]2[ab/c]7 [=] enters and displays the improper fraction 10u2u7
[2nd][%] [2nd][d/c] gives the result as a fraction Result is 18/175

You can also try
10[ab/c]2[ab/c]7[2nd]%][2nd][d/c][=]
Hope it helps

for my 82 i put my fraction in parentheses then press MATH and scroll to >FRAC
