I feel like this is a trick question
In the question it states "Jordan uses 0.08 of the solution for an experiment"
Which means that the answer is 0.08. Jordan uses 0.08 of the solution
50%, if you put it into a calculator 25/50 gives you .50, move decimal 2 times to the right to get 50.
it would be 692,000 even though it may look odd since the place holder for 100 is a 0
B: 2 and 1/6.
Tricky one if you rush through, its meant to SEEM complicated, like a lot of math questions.
