Can someone help me on 1-4

Hi, hope you’re having a good day!
Ok, so the answers are:
1. Meter 100 cents = 1 dollar :: 100 inches = 2.54 meter
2. Astronomer A carpenter uses a saw :: An astronomer uses a telescope
3. Victory Sorrow means tragedy :: victory means to triumph
4. Fish (as you wrote)
I am not so sure about the 1st one only. Good luck!
Thanks for reading and have a great day ❤️❤️
