How to write a formula of several arithmetic operations in excel?

Question

excel

Hello!
Help someone who understands Excel, you need to write the following formula.
We divide the sum of cells L2 + M2 by 2, divide the result by cell J2, then multiply what we got by 100 (i.e. we get a percentage).
Or even better, teach how to solve such problems on your own, where to look, how to google, etc.
Thank you!

Answer 1

It's strange that both respondents made mistakes :)
Here is your formula
However, I do not advise converting to percentages, leave it as a fraction, but for percentages to appear:
Right-click on the cell > Format cells ... > Number > Number formats: Percentage and set the required number of digits after the comma. This will make it easier to work with such numbers.
In order to learn, it is enough to read any Excel textbook for dummies or just Excel help. office.microsoft.com/en-us/novice/FX101820736.aspx - for example.

Answer 2

you select the cell in which the result will be, you start writing the formula by putting = in the formula field, then simple actions using brackets and operators (you can select cells with the mouse)
+ there is help f1 (being in the formula bar) and the formula constructor icon first
I write from the memory of the excel under no hand

John Walkenbach / John Walkenbach - Microsoft Excel User's Bible

Answer 4

=((L2+M2)/J2)*100

Since the order may differ in different languages, it is better to actively use parentheses.
