Answer: Given that most recent age Jack = twelve years Once the most recent period of Sophia = sixteen ages Jack says your dating ranging from his many years and you may Sophia‘s try proportional If the Jack’s many years is actually illustrated from the y and you will Sophia’s age of the x following we are able to make y=kx because they’re compared where k is known as lingering from proportion Today let’s plug offered age per that’s y=twelve and you can x=16 on the y=kx to obtain the constant off proportionality 12=k?16 =k Which is the identical to the considering property value the brand new constant away from proportionality? And therefore Jack excellent in the his statement. But when you consider practical lifestyle state then many years out-of one another will never be equal in porportion Such as for example, immediately following 1 year Jack’s ages could be thirteen and you may Sophie’s decades might possibly be 17 next lingering of proportionality having fun with the fresh new opinions usually become Obviously consequently they are maybe not same.
