12/30 = 18/45, so first you're going to cross multiply and you'll get (30)(18) = (12)(45). Then you can see that 540 = 540 same number so they're proportional...

BTW THIS WAY IS A LOT EASIER.

12/30 = 2/5

18/45 = 2/5

So yes, in summary, they're proportional to each other. Hope this helps, have a BLESSED and wonderful day! :-)

Answer: Carbon

Step-by-step explanation:

Carbon is considered to be the building block of all living things as it is very important in the formation of compounds that are needed by living things to survive such as Carbohydrates and Protein and many more.

This is down to its ability to form stable compounds with other elements such as Hydrogen and oxygen both of which are present in Carbohydrates and Proteins.

Carbon exists in the Earth's crust as Carbonates in water, rocks, petroleum and living things as well especially plants and trees which release a significant amount if they are cut down.
