A bridge is 28 meters long. Find the length of a scale model if the scale is 1 : 550

0.05090909 meters

Step-by-step explanation:

28 is to p as 550 is to 1

is what you should ask yourself

so 550 times p equals 28 times 1 (crossmultiplying)

550p=28

now divide 28 by 550 to find p, the length of the scale model

=0.05090909
