Answer:
Olga's mistake: She did not multiply [tex]\frac{1}{4}[/tex] and [tex]\frac{1}{3}[/tex] in the beginning
Step-by-step explanation:
The main problem is that when a number is outside of the parentheses on the left side, then you have to multiply that number, in this case [tex]\frac{1}{4}[/tex], by both numbers in the parentheses. After that, continue solving the problem as you usually would. Hope this helped!
