Solving percents. I use this to predict gross and net of my paychecks when I do my budget.
Net X
------ = ------
Gross 100
(GrossX) = (Net × 100)
GrossX ÷ (Net × 100) = X
Example;
200 X
------ = -------
250 100
Step A
200 × 100 = 20000
Now 250X = 20000
Step B
20000÷250=80
Therefore X=80
Also expressed as 80% of 250 = 200.
It’s also kinda handy when figuring out sales and stuff at the store, sometimes.
Isn’t that just a solar panel with extra steps?
