How do you do 2 over 3 minus 4 over 9?

Answer 1

2/3 - 4/9=?

-you have to change the 2/3 for they can have the same denominator as 4/9, so you multiple it by 3 so it can change into a 9, and what you do to the bottom you have to do to the top, so also multiple 2 x 3 and you end up with 6/9 - 4/9= 2/9
