Question

what is the difference?

4/3 - 7/9

a.-1/2
b.-1/3
c.5/9
d.11/12

Answer 1

hint:

\[\Large \frac{4}{3} = \frac{12}{9}\]

I multiplied top and bottom by 3

Answer 2

you then would simplify: and you should then get: 12/9 - 7/9 which you would then subtract 7 from 12 which I hope you know how to do ^.^ lol but then youll have your answer with a denominator of 9
