Final answer:
To make a line 5 m long with pencils that are each 0.15 m long, you can fit approximately 33 pencils end to end.
Step-by-step explanation:
To determine how many pencils can be placed end to end to make a line that is 5 m long, when each pencil is 0.15 m long, you would divide the total length of the line by the length of one pencil. The calculation would be:
5 m / 0.15 m per pencil = 33.33 pencils
Since you cannot have a fraction of a pencil, you would round down to the nearest whole pencil, which means approximately 33 pencils could be placed end to end to reach a 5 m length.
