Each day the sharks at an aquarium are each fed 12 pounds of fish for every 100 pounds of their body weight. If a shark at the aquarium weighs 340 pounds, how much fish should the shark be fed?

40.8 lbs

Step-by-step explanation:

First find how many 100 pounds are in the 340 lbs shark.

340/100=3.4

The sharks are fed 12 lbs of fish for every 100 pounds of shark.

There are 3.4 hundred pounds in this shark.

3.4*12=40.8; 40.8 lbs

60: 45 =12: 9 =4: 3 so the answer is 4: 3
