I guess it's easy to miss that m% just means ×m÷100
6% of 50 means 50 × 6 ÷ 100, and because multiplication and division have the same order of operations you can switch them around. so it is also equal to 6 × 50 ÷ 100, in which you can simplify 50 ÷ 100 into 1 ÷ 2, but you could always do that: 50 × 6 ÷ 100 = 1 × 6 ÷ 2.
this "shortcut" however is of extremely limited use. basically for taking a percentage of anything other than things that can very easily divide or multiply 100 like 50 in this example or maybe 10 or 500 it's nearly useless.
Hence 90% of 6 is still hard.
Not really tho. If you know 9x6=54 then it’s pretty easy to get to 5.4 from there
8 and 8 fell on the floor, picked it up, it was 74.
