Pizza palace

Josh is at Enzo's pizza palace. He can sit at a table with 5 of his friends or at a different table with seven of his friends. The same size pizza is shared equally among the people at each table. At which table should Josh sit to get more pizza? (write answer as number - 5 or 7)

Correct result:

x =  5


J5=15=0.2 J7=170.1429  J5>J7  x=5J_{5}=\dfrac{ 1 }{ 5 }=0.2 \ \\ J_{7}=\dfrac{ 1 }{ 7 } \doteq 0.1429 \ \\ \ \\ J_{5} > J_{7} \ \\ \ \\ x=5
