Answer:
Step 2
Step-by-step explanation:
Mario made a mistake in Step 2 when substracting [tex]\frac{1}{3}[/tex] from [tex]\frac{4}{3}[/tex]. When substracting his result ended up being [tex]\frac{2}{3}[/tex] but it is actually....
[tex]\frac{4}{3} - \frac{1}{3} = \frac{4-1}{3} = \frac{3}{3} = 1[/tex]
so the right answer is [tex]q = 1[/tex]
