Oregon is about 400 miles from west to east, and 300 miles from north to south. If a map of Oregon is 15 inches tall ( from north to south), about how wide is the map?
400 / 300 = x / 15
300x = 6,000
x = 20 inches wide
thank you, ms sue, the other question can i do the same way like this
x/36 = 168/21
21x = 6048
x = 288
On a sunny day, if a 36-inch yardstick casts a 21-inch shadow,how tall is a building whose shadow is 168 ft ?
Right.
