make them both fractions with the same bottom number
3-7/8 = 31/8
2-1/4 = 9/4 ( need to multiply by 2 to make it match ) so it becomes 18/8
now subtract 2 top numbers 31-18 = 13 so now you have 13/8
8/8=1 so 13-8 = 5 so the answer will be 1 and 5/8

Answer:
$41,678.09
Step-by-step explanation:
350 X 52 = 18,200
0.0225 X 1,043,507
18,200 + 1,043,507 = $41,678.09
x = total amount of visitors
so we have 90% that lost $100, 9% that lost $1000, now 90+9 = 99%, what's left is just 1% then, so 1% won $10,000.
Profit is Revenue - Cost.
so the profit for the casino, is not who wins, because from the wins the casino needs to pay that to the winner, so they're losing that much, so for the casino, profits is when a player loses, so their profit will come from the 99% that lost money then.
keeping in mind that

since we know that 90% lost $100, that means 0.9x(100) is the total amount lost by all of them, since we also know that 9% lost $1000, then 0.09x(1000) is the total amount lost by them, and the wins are of course just 0.01x(100000).
