Answer:hmm I don’t fully understand what you mean because there is no bottom of the number line it started at zero so all you have to do is fill the line in.
get a clue from the problem statement, figure out what you need to help you solve the problem
Step-by-step explanation:
You need to read and understand the entire problem. Different parts of it give you different clues as to how to arrive at appropriate number lines.
Here are some of them:
groups of 3 red cups and 2 blue cups are circled, telling you that 3 red corresponds to 2 blue, and that this combination is one batch
each number line has 4 tick marks
part b asks for the number of blue associated with 12 red (so you might want to make sure the numbers on the red number line go that high)
part c asks for the number of reds associated with 6 blues (so you might want to make sure the blue numbers go that high)
the questions are about "batches", so the tick marks may want to correspond to batches in some way
The double number line is a tool, just as any diagram is a tool to help you solve a problem. You choose the way you draw it so that it is of help to you in answering the questions asked.
