number unit 1 chapter 2-4

Number

                 

                 For the first time I have been teach by Ms. Nuri, I learn about numbers. I learn how to solve numbers by percentage, fraction, ratio, decimal, and more. I also learn what is the function of number in our daily life. Each of us has been given an assignment, each of us should make a comic about the topic that we have been chosen. In the comic we should make a story of the function of the topic that we have chosen in our daily life. For my comic I have chosen 1;10 ( Direct Number). the story is about a girl has a dept that is bigger than her money and she need to find a way. Her dept is the negative and her money or saving is the positive. She need to use all her saving to pay the dept, then she need to find the rest of the money she need to pay.

"Percent" is like 1 per 100. A percent also can be change into a fraction or decimal. The symbol of percentage is %

Fraction is a part of a whole. For the top number, we call it numerator. Also there is a name for the bottom number called denominator. The denominator number is the number of parts the whole is divided into. Example: Panda bought a pizza for his party. He also invited 5 of his friends. Then he cut the pizza into 10 parts or slice. He wanted to give his friends pizza. How many slice or piece of pizza did his friends got?

Total of friends: 5
Total of pizza slice or piece: 10

Fraction: 

After making the comic  we make a Reading Mathematics about how to solve fraction, decimal and percentage. In this Reading Mathematics, we also need to explain how to solve it and why we use that way to solve the answer.

For the explanation  fraction to a decimal: first we need to know the fraction or the numerator and the denominator or n/d then we need to divide the the numerator with the denominator(n÷d) in case you want to round off the decimal, you need to see the last digit. If the last digit

is 5 or more you need to round it up. But if the last digit is less than 5 then you need to round it down.

Example : 5/3 : 5÷3: 1.666 = 1.667

                                            

            In the note book we learn about percentage. In the percentage we learn how to convert percentage into number or decimal.

-          Finding a percentage of a quantity: to find a percentage of a quantity, write the percenate as a decimal (or fraction) then multiply by the quantity.

Example: 2/100 x 8000: 160
