it’s very often not useful. Like, what’s 6% of 80? See. Still hard. Also, with the 6% of 50 example it’s easy without using this trick. What’s 6% of 100? 6, right? So cut 100 in half to get to 50, and cut the 6 in half to get the 3. Cut the 50 in half again and cut the 3 in half again, and you’ll also know that 6% of 25 is 1.5. Which also lets you know that 6% of 75 is 4.5. the 3 from the 50, plus the 1.5 from the 25. or just know to split the difference between the 3 at 50 and the 6 at 100. A lot of math is just tricks for a thinking process.
