Like fractions are the fractions which have the same denominator and unlike fractions are the fractions which do not have the same denominator.
You basically have to learn separately how to do different things with fractions, including finding a common denominator; converting fractions to a different denominator; simplifying fractions; adding and subtracting fractions; multiplying fractions; dividing fractions.
Assuming you want to use fractions in your equation, let's use an example: 5/7 + 10/7Basically, you don't want it to divide the numbers first then add, because they are supposed to be fractions. Therefore you press the parentheses key and type: "5" "divide" "7" then the close parentheses sign. And you continue on, using the parentheses whenever you are symbolizing fractions.However, if you want to make your answer into a fraction.. it's a lot easier. Simply input whatever you are solving and then press enter. After wards, press the "MATH" key and enter when FRAC is highlighted. It should be #1. And there you have it, using fractions on TI-84 Plus Silver Edition :)
We can only add or subtract fractions if they have the same denominators
With the latest TI-84 updates, you can work with fractions as actual fractions - not operators or decimals. To insert a fraction press Alpha > F1 > 1:n/d. Enter a couple of numbers, press the "+" sign, do it again, press enter, and you will get your answer!
You can enter complex fractions on a TI-Inspire calculator, even though there is not a fraction button. Since a fraction bar essentially means to divide, so the division button is a fraction bar.
if you are looking to put it into a decmial then enter the fraction and press enter then F D artows are inbetween it.

(This does not work with mixed numbers, only fractions and improper fractions.) Type the fraction as a division problem. For example three sixths would look like 3/6. Before pressing ENTER, press MATH and select the first option, >Frac. For example, if you are simplifying 3/6, you will see 3/6>Frac. Press ENTER to see the simplified fraction, in this case 1/2.
To enter mixed numbers, use addition. For example, to enter 23/4 enter (2+3/4) Use parenthesis around it so that the calculator knows that it is all part of one value.
4 x 1/23t = 1/2
7 x 1/9x = 7/6561
1/7 x 3x = 2187/7
1/7 x 3x = 729/7
