Answer:
[tex]\frac{3}{17}[/tex]
Step-by-step explanation:
We have given number of full tables = 17 tables
Number of empty tables =3 tables
Total number of tables =17+3=20 tables
We have to find the ratio of empty tables to the ratio of full tables
So the ratio of empty tables to full tables [tex]=\frac{3}{17}[/tex] here nominator is the number of empty tables and denominator is number of full tables
