Answer 8

when adding fractions you need to get the same denominator
to do this you list numbers in the 9 times table
list numbers in the 3 times table
as they are the denominators
to see the first number that is in both times tables

this will tell you how many times it took in the 9times table to get this value
and how many times it took in the 3 times table

for example
in your case

you have 9,18,27,36,45
3,6,9,12,15,18,21,24,27,30

first number that they share in the times table is 27

in the 9 times table it took 3x9 to get 27
so we multiply top and bottom of our fraction with denominator 9 by 3 to get

\[\frac{ -8(3) }{ 9(3) }\]

in the 3 times table it took 9x3 to get 27 so we multiply top and bottom of our fraction with denominator 3 by 9

to get

\[\frac{ 2(9) }{ 3(9) }\]

Answer 9

thank you guys so much !!!:D i wish i could give u all medals

Answer 10

this gives

Answer 12

simplify all then add
