To find the constant of proportionality of a given relationship, divide the given ratios:
8 grams of yeast for every 500 grams of flour
⇒ 8/500
⇒ 0.016
We can find the constant that is greater than 1 by reversing the values:
500 grams of flour for every 8 grams of yeast
⇒ 500/8
⇒ 62.5
Greater than 1: 62.5
Less than 1: 0.016
