How to draw an angle bisector

Step 1: Locate the original diagram of the angle.
Step 2 :   Locate the  vertex of the angle.
Step 3 :  Place the tip of the compass on the vertex of the angle and draw an arc which cuts each arm of the angle at two different points. 
Step 4 :  Place the tip of the compass on one of the points where the first arc cuts an arm of the angle.
Step 5 : Place the compass' tip on the point of intersection of the first arc and the other arm, without changing the width of the compass. 
Step 6 : Draw a line connecting the vertex of the angle and the point of intersection of the second and the third arcs.

How to convert from a fraction to a decimal

Step 1: Find a number you can multiply by the bottom of the fraction to make it 10, or 100, or 1000, or any 1 followed by 0s.

Step 2: Multiply both top and bottom by that number.

Step 3. Then write down just the top number, putting the decimal point in the correct spot .

How to convert from a decimal to a fraction

Step 1: Write down the decimal divided by 1, like this: decimal/1

Step 2: Multiply both top and bottom by 10 for every number after the decimal point. (For example, if there are two numbers after the decimal point, then use 100, if there are three then use 1000, etc.)

Step 3: Simplify  the fraction

Rules of addition,subtraction,multiplication,division of decimals and fractions

Rules of addition in decimals:
-line up the numbers and decimal point in the same line.For example:
2.33
1.55
0.5
-Add as usual from right to left, column by column.
-Place the decimal point in the answer in line with the other decimal points in the problem.

Rules of subtraction in decimals:
-Add zeros to the right side of the decimal with fewer decimal places so that each decimal has the same number of decimal places.
-a decimal point is placed in the difference such that it is directly below the decimal points in the numbers being subtracted

Rules of multiplication in decimals:
-Sometimes you need to write one or more zeros in the product before you can place the decimal point.
-You can write as many zeros as needed to the left of the product to place the decimal point.

Rules of division in decimals:
-If the divisor is not a whole number, move decimal point to right to make it a whole number and move decimal point in dividend the same number of places. 
- the decimal point in the answer is going directly to the dividend.

Rules of addition in fractions:
-If its the same denominator just add them ,but if although is the same denominator number and the addition of the numerators results are bigger than the denominator number need to simplify,but in some case not.
-If its not the same denominator and numerators number like two different numbers,added and at the end if the numerator addition result is bigger than the denominator number need to simplify,but in some case not.
-The addition of fractions are in the same line .For example:
2/3 + 4/3 =

2      4      6
-  +  -   =  -
3      3      6

Rules of subtraction in fractions: 
-To subtract fractions in some case that the denominators are the same so,just subtract.

Rules of multiplication in fractions :
-To multiply in fractions need to multiply those numbers in "x".
-If the answer of the numerator is bigger than the denominator need to change it into equivalent fractions.

Rules of division in fractions :
-In the case of dividing fractions need to re-write the fraction and the solve it.
For example:
2     2    2             1    2    1     2
-   ÷   -  =  -   multiply by -  =  _      _  =   _
5      1   5              2   5     2   10

What kind of scientist do you wanna be? and why?

If I have an opportunity to be a scientist i want to be a meteorologist ,because i want to study about weather and climate.I want to study about weather ,like searching about climates information just like to know how something causes the rain how it causes natural causes about nature . Weather and climate is also part of nature because nature includes the environment.Weather is not the same as climate because weather means the temperature and  climate means if its rainy day , sunny day or alot of clouds.


Its important the topic of being a meteorologist to me because i want to know more about nature ,but the thing is that being a scientist is not that easy it needs to be study alot and there is alot of hurts in the brain that makes you think alot . An meteorologist its also study about phenomenon's occurred example like and tsunami its part of the study of climates.


An meteorologist not only study about the weather and climates also they educate like told people about the earth's atmosphere and climate.Many of the televisions shows the climate forecaster that people who is telling us the climate is the meteorologist.



This is all of the information's that i can find !

Science histoy of science

*to write an important event from the history of science that you think is important to you.

The most important event for me is the evolution of science because when its starts first the science is something about environments ,natural causes,and etc.But people of the entire world believes in the natural world,the earlier contribution of science first was made in Greek.It was hard for them to think about something of science before the scientific method because if you work in science or to discover something you will need a method to go on discover and research for that so, to me the scientific method was reall important in the evolution of science because its gave us a perfect conclusion.The evolution of science tooks place in Europe start in the 15000s. A Greek philosopher called Thales he had been called the father of science because from his ideas of the natural world,he saids that the earthquakes and lightning have their own natural causes.Then an Persian scientist called Geber he introduced the scientific method and experimentation in chemistry.The science evolution begins in the solar system like they start with the topic of the solar system of how the sun is moving around the planets and how is being back to the center.Then Albert Einstein begans rocking on it like doing more inventions (bringing more information about science) to us ,he published his general theory of relativity its explain about the gravity of the solar system and about time.
