What I Have Learned About Grade 9 Fractions
Fractions On a Number Line
Fractions on a number line was confusing at first but when I was trying a couple of examples I was doing fine and grate. The negatives on a number line are really the same thing as the positives.
Comparing Fractions
For comparing fractions I just wrote it down on paper but ill just say it here as well. When its a negative fraction vs. a positive fraction, the negative fraction will win because negatives are more bigger and powerful than the positive ones, the more number it goes down the powerful it gets. In this picture I have 
Adding+ Subtracting Fractions
For adding and subtracting fractions the key thing you will need is a common denominator! Common denominators are really important when dealing with equations like this. But when you have the same denominator you add or subtract what ever the sign is. So much better when you have the same denominator.
Multiplying And Dividing
Multiplying fractions are super easy! there are many ways to get your answer for example cross- cancelling it. You could also just multiply top by top bottom by bottom, this is how i see multiplying fractions.
Dividing!
Dividing is the same thing as multiplying because you change it into a multiplication question, you change it by flipping (reciprocal) the second fraction. then you can multiply top by top and bottom by bottom.
The other thing that I learned in math this unit is identifying rational numbers, and rational numbers have to do with positive and negative numbers it also means that it can be expressed as a quotient/ fraction. For example these are rational numbers -5, 9, 3/4, 0.36 (decimals are also rational numbers), 1.4, 5/8….. and so on. To me rational numbers just mean numbers in all shapes of form, that’s how I picture it. Comparing rational numbers was not hard at the beginning because the first thing you had to do was look for the bigger number and that’s when you know its bigger than the other.
