Answer:
Step-by-step explanation:
When you want to make a graph to separate things or sizes. E.g. to collect data of people’s shoe sizes and then separate them to see how many people have what size
I can’t necessarily draw a model, lol but I can try my best to type one.
12/(1/3)=12•(3/1)=36
What do you mean picture?
You could do this with two weighings assuming its a two pan balance - (1) place three balls on each side - if they balance out then its the remaining three that has abnormal ball (2) out of that group, place one ball on each side - if balances it out, the abnormal ball is the remaining one.
If the weighing in step (1) does not balance out, grab the group of three balls that is light or heavy and repeat step (2) described above.
