Now we have two simple equations: 1) 18=100%. 2) x=25%. where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that: 18/x=100%/25%. 6. Now we just have to solve the simple equation, and we will get the solution we are looking for.o get the solution, we are looking for, we need to point out what we know. 1. We assume, that the number 18 is 100% - because it's the output value of the task. 2. We assume, that x is the value we are looking for. 3. If 18 is 100%, so we can write it down as 18=100%.
Sumatra (also spelled Sumatera) is an island in western Indonesia, westernmost of the Sunda Islands.
The largest islands are the Kalimantan provinces on Borneo, Sumatra, Papua, Sulawesi and Java (where Jakarta is located). Nearly 60 percent of Indonesia's land is forested and a significant portion is mountainous and volcanic. The highest point is Puncak Jaya in Papua, which is 5,030 meters tall. Some other mountains on Sumatra and Papua exceed 3,000 meters in height.
