4 - Microwave Miracle
Patrick believes that fish that eat food exposed to microwaves will become smarter and would be able to swim through a maze faster. He decides to perform an experiment by placing fish food in a microwave for 20 seconds. He has the fish swim through a maze and records the time it takes for each one to make it to the end. He feeds the special food to 10 fish and gives regular food to 10 others. After 1 week, he has the fish swim through the maze again and records the times for each.

Answer (3)
No because u would multiply to get a common denominator and it would be 4/6 5/6
no they are not because 2/3 is equal to .6 and 5/6 is equal to .83 ;
The ratios 3 2 and 6 5 are not equivalent. When converting 3 2 to have a common denominator, it equals 6 4 , which is not equal to 6 5 . Hence, they represent different values and are not equivalent ratios.
