To solve this problem, we need to follow a few steps:

Step 1: Convert Canadian dollars to US dollars.
Since Greg exchanged 200 Canadian dollars for a fraction of US dollars, we need to find out how much he received in US dollars. Using the information given, Greg received 1/5 fewer US dollars. Therefore, we can find the amount of US dollars by multiplying 200 by 1 - 1/5, which is 4/5.
Amount of US dollars Greg received = 200 x (1 - 1/5) = 200 x (4/5) = 160 US dollars.

Step 2: Calculate the amount of US dollars spent.
Greg spent 3/4 of the US dollars he received. To calculate this amount, we multiply the number of US dollars by 3/4:
Amount of US dollars spent = 160 x (3/4) = 120 US dollars.

Step 3: Find the amount of US dollars remaining.
Since we know the total amount of US dollars Greg originally had and the amount he spent, we can calculate the amount remaining:
Amount of US dollars remaining = Amount of US dollars received - Amount of US dollars spent
Amount of US dollars remaining = 160 - 120 = 40 US dollars.

Therefore, Greg has 40 US dollars left.
