Soup from canteen

For how many people is 90 liters of soup enough if we assume 3/8 liter of soup per person in the canteen?

Correct result:

n =  240

Solution:

V1=90 l V2=3/8=38=0.375 l  n=V1V2=900.375=240V_{1}=90 \ \text{l} \ \\ V_{2}=3/8=\dfrac{ 3 }{ 8 }=0.375 \ \text{l} \ \\ \ \\ n=\dfrac{ V_{1} }{ V_{2} }=\dfrac{ 90 }{ 0.375 }=240
