Ok i understand how the answer is calculated

R :: 40\*.5 = 20 television sets
T :: 50\*.9 = 45 television sets

45\*x = 20
x = 0.44 or 44%

so R sold 44% of what T sold but it's asking "what percent less" ? i know the answer is 56% which is 1 - .44 = .56 or 56% but i'm having trouble grasping what it actually means by what percent less . . .
