Question

A field is 3645 feet long. What is the length of the field in yards?

Answer 1

1215 is how many yards it would be

Answer 2

we know that

`1\ yard=3 \ feet`

so

by proportion

Convert
`3,645\ feet` to yards

`(1)/(3) (yard)/(feet) =(x)/(3,645) (yards)/(feet) \\ \\x=3,645/3 \\ \\x=1,215\ yards`

therefore

the answer is

`1,215\ yards`
