There are 19 guests at Levi's party. If each guest will be served exactly one third​ 1/3 pint of ice cream, how many pints of ice cream will he need?

The number of pints needed for each guest will be 1/3 pint/guest x 1 guest = <<1/3*1=1/3>>1/3 pint.

So, Levi needs 19 guests x 1/3 pint/guest = <<19*1/3=6 1/3>>6 1/3 pints of ice cream. Answer: \boxed{6 \frac{1}{3}}.

To find out how many pints of ice cream Levi will need, we can multiply the number of guests by the amount of ice cream each guest is served.

Number of guests: 19

Amount of ice cream per guest: 1/3 pint

So, to find the total amount of ice cream needed, we multiply 19 by 1/3:

19 * 1/3 = 19/3

Therefore, Levi will need 19/3 pints of ice cream for his party.

To find out how many pints of ice cream Levi will need for the party, we need to multiply the number of guests by the amount of ice cream each guest will receive.

Since each guest is served 1/3 pint of ice cream, we can convert this fraction to decimal by dividing 1 by 3: 1 ÷ 3 = 0.3333 (rounded to four decimal places).

Now, we can multiply the decimal value (0.3333) by the number of guests (19) to find the total amount of ice cream required: 0.3333 × 19 = 6.3333 (rounded to four decimal places).

Therefore, Levi will need approximately 6.33 pints of ice cream for his party.
