## Percentage and Angle

Round 3 of math class I have learned about the percentage and the angle. Percentage is the number that they use it to represent the number stand for 100. The sign of percentage is this(%) . In percentage lesson I learn how to change the fraction to percentage , how to using the percentage to know the price of something that we buy that is discount. And  also how to use the percentage to stand for something that have a lot of number. After i finish study the percentage i’m study about the angle. Angle is the two line that come together to meet at some point and it represent by the(°) degrees  . They are four properties or rules in angle . which are supplementary angle , complementary angle, vertically opposite and the other not name and it just called Angle.

• Supplementary angle is an angle that add up to 180°.
• Complementary angle is an angle that add up to 90°.
• Vertically opposite is an angle that is have equal side.
• Angle is a round a point that add up to 360°.

And I also learn how to measure the angle. After study about this i feel it really cool to study about the percentage and the angle. It really fun whenever i study about the angle and percentage because angle and percentage is helping people a lot in everyday life.

## Math

Math class is one of my favorite class. In round two of the school years I have learn a lot of thing but one of my favorite thing that I love in math class is Ratio. Ratio is the study of the the quantitative relation between two amounts showing the number of times one value contains or is contained within the other. That mean in this project of class I focus how to compare thing and thing. While we study about that my teacher also give us some work on the class , such as finding the number of the student and the teacher also finding the ratio of the ingredient of the food . Beside that I have learn about how to measuring the Area and perimeter of triangle square rectangle and the polygon. By the way I also learned about the how to find surface area of the all the geometry . And to know more about that my teacher also give us the word Khan academy and also the code.org to know more about the about the Algebra. And also we do some of the review thing like Multiple,Subtract,Addition and the Division.
