Key ideas

percents can be combined by adding to solve a problem 5%+7%=12% .to calculate the increase of a # .you can add the combined percent amount to the original # .percents of percents can be used to determine amounts that result from consecutive percent increase or decrease .you can multiply the original # by a single percent greater than 100 [eg. 112% of 100= 1.12x 10 = 112

THE FINAL SALE

3. 1st I found 10% then add it to 100 . Then I found 15% then added all of my answers together which gave me 100.25

Now just find 25% of 100 then add it to 100.25.

BUILDING SQUARES

the girl told us to cut out 2 perfect 10x10 squares and 2 10x8 squaresand 2 2x10 squares. Then he told us to colour the 2 10x10 squares . Then put a 10x8 square with a 2x10 square and colour it a different colour . Then we had to put the perfect 10x10 squares away and keep the 10x8 squares along with the 2x10 squares.

And after you need to glue the paper in the yellow sheet. Then right 0.1 beside the paper that you glued in the yellow paper.

To find the area of a square, you must square one of the sides.

E.g 2 squared = 4

Squaring a number means to multiply a number by itself.

In class, we had to find out what was the biggest square we could make with 2 squares.

I found out that a 1.4 by 1.4 square is the biggest square we could make. I had four squares left over.

In this scribe we had to Show some examples of answers that were wrong.
-Like What was your mistakes.-How will you remember what to do in future tests.


My mistake was not reading the question correctly and also not studying alot.
-To inprove this I will study ,and read the questions more than once in order to get it.



1. In a group of 84 students surveyed, the ratio of students preference is seven oatmeal eaters to four granola eaters to three toasted 0 eaters.

-of 84 students, how many prefer oatmeal ?

-Of 84 students, how many prefer granola ?

-What percent ( to one decimal place ) of the group prefers toasted 0's ?




2. A rapid transit has 17 passengers on it as it starts to run. At the first stop 3 passengers get off and 37 passengers get on. What is the ratio of the number of passengers who were on the train as it arrived in the station to the number who were on the train when it left the station?Express your answer in the lowest terms?

a) What is the ratio of the passengers who

got off the bus compared to the original

number on the bus? Show the ratio in

lowest terms.

Passengers going off 16:48 16/48 In simplify : 1:3 1/3

b) What is the ratio of the passengers who

got on the bus at the stop compared to

the new total then on the bus? Write

your answer as a fraction, a decimal,

and a percent.

Question: How much money in side the glass and what are the differences of it?

Answer: the differences is if you put

width on the glass so you can put more than

a hundred dollars Mr. H says the answer that

inside the glass is a 100$

And I think there is more 10 cents than the pennies

If divide 100÷2=50$ but there is another way to do it

if you gave 10 $ to each people you got 100 $

1 =10

2 =10

3 =10

4 = 10

5 = 10

6 = 10

7 = 10

8 = 10

9 = 10

10 = 10

you got 100 $

Amiel Scribe post four4s

This is the write Equation cause if you divide 4 to 4 is equal 1 and make another one of that then you have the answer.

Same:they have the same equation and they both use the same operations

Differences:they don not equaled by two because if you write this 4 ÷ 4 + 4 ÷ 4= 1.25 so that

equation is wrong and this equation is write because if you put brackets around the four like this

(4÷4)+(4÷4)=2 this equation is write and not same sign.

Graph B, the numbers go up by 100 s

B) There 's not much differences b/w the two

Graph A is just 5% less than GRAPH B

C) Graph A because it starts from a lower number and

pattern's not that hard ti find out
