Answer :

Well, 4/10 is equal to 0.4
0.45 does not equal 0.4, so no, Jayne is not correct. Hope that helps :)
The question is asking to state if the said conversion by Jayne is correct and base on my calculation and further computation, 0/45 is 45/100 so its not 4/10, base on that, Jayne is not correct. I hope you are satisfied with my answer and feel free to ask for more if you have questionsÂ
