1) In school, you will encounter percentages on class assignments to see how much progress you made in an subject.
2) On a cell phone, you encounter percentages by how much your cell phone is charged in order to know if you need to charge the battery or not.
place 325 on top and line up 52 with 25 on bottom. Then multiply 2 with 5 to get 10. Place the zero bellow the line and carry the 1 over the 2. Multiply 2 times 2 to get 4 and then add one to get 5. Put the five bellow the line. Multiply 3 times 2 to get a total of 6 and bring it bellow the line. Bring a zero bellow the 0 that's bellow the line. Multiply 5 times 5 to get 25. Bring the 5 to the left of the zero you just placed and carry the 2. Multiply 5 times 2 to get 10 and add the 12. Place the 2 to the left of the 5 you just placed bellow the line and carry the 1. Multiply 5 times 3 to get 15 and add the 1 to get 16. Place the 16 to the left of the 2 you just placed bellow the line. Then add 650 plus 16250 to get an answer of 16,900.
Wow that was long and hard to explain LOL. :)
Step-by-step explanation:
You need to know some geometry rules.
For example:
Angle sum of a triangle is equal to 180 degrees.
Straight line is equal to 180 degrees.
Other rules I have attached.
If you have any confusion over these I will be happy to answer your questions.
The perimeter of the right angled triangle should be 36cm, hope this helps:)
