Hey there!
We can utilize division and fractions to find the original scale and the new scale of this situation.
For the original scale:
, meaning that for every 18 inches on the map, the length of the courtyard would measure 54 feet
We can divide this fraction by a greatest common factor of 18 to get it to:
, meaning that for every 1 inch on the map, the length of the courtyard would measure 3 feet
For the new scale:
, meaning that for every 18 inches on the map, the length of the courtyard would measure 72 feet
We could also divide this fraction by a greatest common factor of 18 to get it to:
, meaning that for every 1 inch on the map, the length of the courtyard would measure 4 feet
So, the scale went from to , or from 3 feet in the first scale to 4 feet in the second scale.
Your answer will be D.
Hope this helped you out! :-)
