Question 878526
Otis' measure is 3 times as long as Jason's.  It is represented as a 1:3 ratio.
.
Think of it this way.  Otis has a yardstick.  The field that he measures is 100 times the length of the yardstick.  Jason has only a ruler (measuring one foot).  When he measures the field, it is 300 times the length of his measure.  They're both the same distance.  The ratio of the yardstick to the ruler is 1:3 -- every one measure of the yardstick is 3 measures of the ruler.
