Hi all,
Once again I am stuck on a question which I am not able to work it out for my child.
"Michael is baking 240 cakes for the school fair and Zara is decorating them. She ices every 4th cake in pink icing.
She puts silver sprinkles on every 5th cake and every 3rd cake she adds white chocolate star.
How many cakes in total will have pink icing AND silver sprinkles AND white chocolate star?"
Below is how I was aiming to trying to make my child visualize the pattern, and assumed that to get the answer I need to find the line where it has all the three (i.e star, pink and silver sprinkles).
I began with 12 cakes, hoping it will be smaller number and proportionally equal to 240. By looking at this we can work out individual type of cakes for example 4 cakes with star (12/3), 4 cakes with pink (12/3) and 2.5 ? cakes with sprinkles (12/5)....but I just cannot figure out how to get number of cakes with all of them.
cake 1 - first>>>>>>>>first>>>>>>>>>>first
cake 2 - second>>>>>>second>>>>>>>>second
cake 3 - third (star)>>>>third>>>>>>>>>third
cake 4 - first>>>>>>>>fourth(pink)>>>>>fourth
cake 5 - second>>>>>>first>>>>>>>>>>fifth (silver sprinkles)
cake 6 - third (star)>>>>second>>>>>>>>first
cake 7 - first >>>>>>>third>>>>>>>>>>second
cake 8 - second >>>>>fourth (pink)>>>>>third
cake 9 - third (star)>>>first>>>>>>>>>>fourth
cake 10 - first >>>>>>second>>>>>>>>fifth (silver sprinkles)
cake 11 - second>>>>>third>>>>>>>>>first
cake 12 - third (star)>>fourth(pink)>>>>>second
any help could do please,
