Is double 200 percent

'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'.
