You set up a proportion problem... 30/ Y = 60/100 You are solving for Y and the 60/100 represents 60% You just cross multiply (i.e. 30 x 100 = 3000) And divide (i.e. 3000 / 60 = 50) This is your answer! 30 is 60% of 50

'Double' is an English language word that means multiply by '2'. Another English language word that means the same is 'twice'. Casually , 200% means 'double/twice/multiply by '2' of 100% However, in correct mathematics, there is no such number as 200% . 100% is totality. If any value becomes greater than 100% , then it is multiplied by the given value of increase. e.g. 125% (Ugh!!!!) means 100 x 1.25 = 125. NB Similarly , 'Triple' means multiply by '3'. The same as 'thrice' , which also means multiply by '3'. There is no corresponding word for '4' or greater'.
