Best Math Trick I've Ever Learned by Eazybay(m): 6:11am On Nov 29, 2018 |
Ever tried calculating your % share in a deal without using a calculator? It could get really messy and confusing. So here's the trick... Reverse your percentage calculations. For example, without using a calculator, please tell me, how much is 8 % of 50? You’re probably thinking, 8/100 x 50. Try to cancel out and then you have 8/10 x 5. Before you do 8 x 5 ÷ 10. Which gives us 4. Now let's use the reverse percentage trick. 8% of 50 is the same as 50% of 8! Using the reverse percentage, many of us already know 50% is equal to 1/2. So 50% of 8 is simply 1/2 x 8. It’s exactly 4. I didn’t use my calculator. It holds true for all numbers. Go ahead, try a few. 80 % of 50? 30 % of 25? In some cases it greatly simplifies the calculation or makes it easier to approximate the result. Yes, it works with numbers greater than 100. For example, 5 % of 2000 is the same as 2000 % of 5 (20 x 5). QED. PS: Register For The 2019 edition of the Campus Metro National Bee and win 1,000,000.

Well, I've also got one for my fellow mathematicians in the house... Do you know anything multiplied by '11' is simply adding the two integers and putting the result in the middle? 11 x 11 = 1+1 = 2; Thus... 1 2 1 11 x 34 = 3+4 = 7; Thus... 3 7 4 11 x 27 = 2+7 = 9; Thus... 2 9 7 Argue with your keyboard...

An educative thread like this will not make FP but if it were to be anything about Tonto Dike, Toke Makinwa & Bobrisky, it would. |
