Question

An 8-foot piece of rope is cut into sections that are 8 3 83 feet long. How many sections of rope are there?

Answer 1

B) 299 sections with 19 feet left over

Step-by-step explanation

To find the number of sections we have to divide the length of the rope by the length of each section:

`(6298)/(21)=299.9047619`

The whole part of this result is the number of 21-foot sections we'll have. If we multiply the decimal part by 21 we can find the length of the rope left:

`0.9047619*21=19`

We have 19 feet left of the rope after cutting 299 21-foot long sections
