Step-by-step explanation:
part A you start at 8 from the first participant then you take away one from the last one. you add up all the numbers up to get the answer. 8+7+6+5+4+3+2+1=36.
part B the first part is 1x1x1x1x1x1x1x1=1. the second part is 8x7x6x5x4x3x2x1= 40,320. the third part is 1/40320

You have ounces and you want kilograms, so you need to multiply by a conversion factor that has ounces in the denominator and kilograms in the numerator. In order to keep from changing the value of the quantity you have, the conversion factor must have equivalent quantities in the numerator and denominaotr.
Your problem statement tells you that both 0.454 kg and 16 oz are equal to a pound, so they are also equal to each other. Their ratio (with kg on top and oz on the bottom) is a suitable conversion factor.
The best choice is ...
724 kg
