So when I went to the practice: writing proportional equations, it said "A unicorn daycare center requires there to be 2 supervisors for every 18 unicorns. Write an equation that shows the relationship between the number of supervisors (n) and the number of unicorns (u). I put n=9u because n= 1 supervisor and 9u= 9 unicorns. Speed and travel time are Inversely Proportional because the faster we go the shorter the time. As speed goes up, travel time goes down. And as speed goes down, travel time goes up. This: y is inversely proportional to x. Is the same thing as: y is directly proportional to 1/x. Which can be written: y = k x.A constant of proportionality is a number that relates two quantities in a proportional relationship. For example, if we say that y is proportional to x , we might write the equation y = k x , where k is the constant of proportionality. The constant of proportionality is another name for the unit rate. Suppose Zion skips rope at a constant rate ...

Well you put 1,000,000 in right over here, multiply it by two, you get your cups of milk. You're going to need 2,000,000 cups of milk. And you can see that this is a proportional relationship. To go from number of eggs to cups of milk, we indeed multiplied by two every time. That came straight from this equation.
