A sidewalk is 40 m long. each section of the sidewalk is 8 dm long. how many sections of sidewalk are there?

50

It’s 50

To find the number of sections of sidewalk, we need to divide the total length of the sidewalk by the length of each section.

Given:
Total length of the sidewalk = 40 m
Length of each section = 8 dm

First, we need to convert the length of each section to meters since the total length of the sidewalk is given in meters.

1 decimeter (dm) is equal to 0.1 meter.
So, 8 dm is equal to 8 * 0.1 = 0.8 meters.

Now, we can divide the total length of the sidewalk by the length of each section to find the number of sections.

Number of sections = Total length of the sidewalk / Length of each section
Number of sections = 40 m / 0.8 m
Number of sections = 50

Therefore, there are 50 sections of sidewalk.
