i knew 210 is 700% of 30, because its 7 times bigger than 30, so our answer is 600% bc there is already 30 as 100%, we need 210-30=180, and 180 is straightly 600%

Because you're thinking what percentage 210 is of thirty, you want the percent change. Since 180 is the change, 600% of 30 is 180.
Because 210 (is) 700% of 30 and it is grater than 30 600% since 30 itself is100%

150= 500 %
180= 600 %

210 is 700 per cent of 30. And if we subtract 210-30, it's gonna be 600 per cent. So 210 is 600 per cent greater than 30. So finding the difference between the starting value and the ending value is an easier way to do this just like I did.
