The egg of a hummingbird typically is \(1.3\) cm long and \(0.9\) cm wide. The Philippine Goby is about \(0.9\) cm long. It can be found in the Philippines and other Southeast Asian countries. The smallest known jellyfish, Irukandji, has a bell size of \(0.5 – 2.5\) cm. Its tentacles can be as long as \(1\) m. They are found in Australia. Its venom can be fatal to humans. The Wolfi octopus, also known as the Star-sucker Pygmy Octopus, is the smallest known octopus in the world. Their typical size is around \(1 – 2.5\) cm and they weigh less than \(1\) gm. They are found in the Pacific Ocean.
1.Unit Conversion:
The Irukandji jellyfish can have tentacles as long as \(1\text{ m}\). Convert this length into centimeters (\(\text{cm}\)).
2.Decimal Subtraction & Comparison:
The egg of a hummingbird is \(1.3\text{ cm}\) long, while the Philippine Goby fish grows to a length of about \(0.9\text{ cm}\). Find how much longer the hummingbird's egg is compared to the length of the Philippine Goby fish.
3. Multi-Step Challenge:
If the smallest Irukandji jellyfish has a bell size of \(0.5\text{ cm}\) and the largest has a bell size of \(2.5\text{ cm}\), find the difference between their sizes. Express this final difference in millimeters (\(\text{mm}\)).
