Answer: Mike bought 120 pounds of fish and Millie bought 30 pounds of fish.

Step-by-step explanation:

If the ratio is 8 to 2 then 8/10 will be the probability of Mike buying fist and 2/10 will be the probability of Millie buying fish.

Now multiply each fraction by the total number of pounds to find how many pounds each bought.

8/10 * 150 = 1200/10 = 120

2/10 * 150 = 300/10 = 30

In this case, Mike bought 120 pounds of fish and Millie bought 30 pounds of fish.
