Question

A rectangular field has a length of 105 feet and a width of 60 feet. On a map of the field, the width was drawn as 4 inches. What measurement should represent the length?

Answer 1

60/4=15
105/15=7
Therefore the length is 7 inches

Answer 2

`(4)/(x)  x   (60)/(105)`

105 x 4 =60x
420 = 60x ( Divide 60 on both sides to get x by itself)
7 = x

The length should be 7 inches

Hope this helps :)
