# what i have learned about grade 9 fractions

• if its addition and subtraction you have to make the denominator the same and you have to make it equavelent too.  $\frac {-6}/{-4}$
• tug of war $\frac {-5}+{9}$
• just do it- its when it a multiplication question
• operations with integers, multiplication and division
• speed multiplication, for speed multiplication you have to divide the denominator and the numerator to make it the smallest fraction.
• we learned how to put fractions on a numberline and we also learned how to compare fractions. for a numberline you make the same denominator, for comparing fractions you also have to make it the same denominator and you can tell which ones bigger.
• we learned how to divide and multiply fractions together, for divsion u make it into a reciprocal fraction and you multiply. for multiplication you can just multiply straight across. Divion= $\frac {-5}{8}\div\frac{5}{3}$
