Question

Calculate it 100‰ – 100‱ ​

Answer 1

Answer:

you can set up a proportion that says20%/500 = 100% / xif you solve for xx = (100% * 500)/20%therefore x = 2500and you can check that because you know that 20% is 1/5th of 100%, so 1/5th of 2500 should be 500, which it is.make sure your units always stay lined up (in this case the % since I opted to use 20% instead of 0.2).
