One (half 438) kilograms = 219 kilograms
219 / 65 = 3,37 hours = 3 hours 22 minutes and a few seconds.Three and a half hours
The percentage of 78% of 219 = 100*(78% of 219) = 100*(219*78/100) = 219*78 = 17082%The percentage of 78% of 219 = 100*(78% of 219) = 100*(219*78/100) = 219*78 = 17082%The percentage of 78% of 219 = 100*(78% of 219) = 100*(219*78/100) = 219*78 = 17082%The percentage of 78% of 219 = 100*(78% of 219) = 100*(219*78/100) = 219*78 = 17082%
39% of 219= 39% * 219= 0.39 * 219= 85.41

Thorium-219 has a half-life of about 1.4 minutes. To calculate the time it takes for a 2kg sample to decay to 15.6g, you would need to use the radioactive decay formula. This would involve determining the number of half-lives it takes for the 2kg sample to decay to 15.6g.
39% of 219= 39% * 219= 0.39 * 219= 85.41
219-g= 219-g
161/2 ÷ 62/3 = 219/40
303-219 = 84
219-77 = 142
What should happen is that you are asked to express 219 in some context. 219 what? Bits of work that you did not hand in? 219 mistakes on a single page? 219 marks out of 220 (excellent!) or 219 marks out of 2,000 (pathetic!).
