What is the ratio of the lengths of two pipes measuring 150 m and 100 m?

To determine the ratio of the lengths of the two pipes, you need to compare the lengths directly. The lengths of the pipes are 150 meters and 100 meters.

The ratio can be calculated by dividing the length of the first pipe (150 m) by the length of the second pipe (100 m).

So, the calculation is as follows:

150 m / 100 m = 1.5

This results in a ratio of 1.5 to 1, which signifies that the first pipe is 1.5 times longer than the second pipe.

In this context, the correct answer reflects a straightforward comparison of the two measurements. Other choices do not represent this relationship as accurately, and therefore they are not suitable.
