Thank-you. I've been putting off actually learning this for decades. It's silly how it only took 5 minutes of focus to finally lock this item away. Credo: What can you do today to make yourself better? For me, today, it was learning something I should have learned long ago but didn't because every time it came up, it was too inconvenient to do the actual research and thinking rather than just cast around in the dark because I needed a number right away for whatever I was in the middle of. Life goes fast, doesn't it? What other silly bits of lingering ignorance would take five minutes to lock down?
Be careful, 80 x 1.2 = 96 and not £100, so I wouldn’t recommend that. If you are doing reverse percentage questions, you should try one of the approaches in the video.
