Explanation:
The problem states that 20 burgers can fees 15 kids, we can write this as a proportion between the number of kids and the number of burgers in fraction form
Then, we need to find the number of burgers x for 80 kids, following the same previous proportion, the number of kids (80) is the numerator of the fraction, and the number of burgers is the denominator
The two expressions must be equal, therefore, the proportion is
[tex]\frac{15}{20}=\frac{80}{x}[/tex]
which is the first option.
Answer:
[tex]\frac{15}{20}=\frac{80}{x}[/tex]
