Answer: Since the newest ages of Jack = several years Since the current age Sophia = sixteen age Jack claims that the relationship ranging from his decades and you will Sophia‘s is proportional If Jack’s ages is actually represented from the y and you may Sophia’s years from the x up coming we can establish y=kx because they’re equal in porportion in which k is called constant out of ratio Now let’s plug considering ages of for every single that is y=12 and you will x=sixteen toward y=kx to find the lingering of proportionality several=k?16 =k Which is the identical to new offered value of the fresh ongoing of proportionality? And therefore Jack is useful throughout the his statement. But if you contemplate important lifestyle condition then the many years off both will never be compared Eg, after 1 year Jack’s decades might be thirteen and you can Sophie’s decades could well be 17 following ongoing away from proportionality using the fresh beliefs will become Demonstrably and therefore are perhaps not exact same.

We then add 0.twenty five to portions or if you bullet you can buy on 18 portions. 18 + 0.25 ? 8 = 18 + dos = 20
