I don't quite understand what to place in the denominator for a question like this in which there is no clear order. Does 120 go on the denominator because of the position of "is what percent less than a number that i..."?

Translating word into math
The number that is 50% greater than 60
x = 60.1.5 =90
is what percent less than a number that is 20% less than 150?
and \(90 = \frac{x}{100}\) of a number that is 20% < 150 which is 120
Joining altogether
\(90 = \frac{x}{100} 120 =75\)
But the question asks you percent less than a number
So this number must be 25 % less because our number is 75. 75+25=100
You must have a balance

Hi Carcass,
so if the question was to read "The number that is 100% greater than 60 is what percent greater than a number that is 40% less than 150?"would the answer be 120-90/90 = .33? "greater then" so the lesser of the two values goes in the denominator
would you also agree with these?
"x is what percent greater than x-2" = x/x-2
"y-3 is what percent less than y" = y-3/y
