Why did nobody tell us that percentages are completely reversible? This math cheat code will save your life. Quick, what is 16% of 50? Doing that in your head is a total nightmare, right? Wrong.
Just flip them. Flip the numbers and change it to 50% of 16. 50% is half, so what's half of 16? It's eight, which means 16% of 50 is also eight. It works every time. Just look for these friendly percentages to flip to. Check the pinned comment.
