How to add fractions on calculator?

Calculators can't show the answer in fraction form, but you will get the answer in decimal form if you added it as: (number/number)+(number/number).

Question

How can I see fractions or write fractions on a calculator?

Community Answer

Calculators don't allow you to insert fractions as such. All you can do is enter the numerator, then the division sign, and then the denominator. It will display the decimal equivalent of the fraction. (Fractions really mean division.)

You would need a calculator that allows you to enter variables. Most calculators don't allow you to do that. However, if you type it on Google, Google will solve the problem for you.
