For example, if 500 lbs. of food will feed 20 animals for a week, for how many days will 200 lbs. of food feed 14 animals? Which is the constant? All the numbers are different.

20 500 7 14 200 ? 20/14 inverse proportion as no.of animals decrease days will increase. 200/500 direct proportion as the quantity decrease,days will also decrease. 7*(20/14)*(200/500)=4
