To compute for the debt-to-GDP ratio, we just have to divide the debt given in this item by the GDP and convert the quotient to percentage. That is, debt-to-GDP ratio = (9,529,034,179,824,022)/ (16,247,683,987,248,007) x 100% debt-to-GDP ratio = 58.65% Thus, the answer is FALSE.
There's probably better ways but you can estimate by knowing 30*3=90 so it should be somewhere pretty close to 30. Guess and check with basic calculations to get 28, 29, and 30.
