Answer:
[tex]\frac{7}{9} =\frac{91}{x}[/tex]
Step-by-step explanation:
In a proportion, you want to keep the same types of items on the same side of the fraction bar. In this, case you would want to keep the values for the burritos as the numerator for the proportions and the values for the tacos as the denominators for the proportions.
Here's how it should be set up:
x=number of tacos sold that night
[tex]\frac{7}{9} =\frac{91}{x}[/tex]
As you can see, the numbers that represent burritos are in the numerator for both proportions and the values for tacos are in the denominator for both proportions.
