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?
PLEASE HELP AND EXPLAIN IT
Set up a proportion:
15/300 (the ratio of inches to miles, north to south)
and x/400 (the ratio of inches to miles, west to east)
Therefore,
15/300 = x/400
Can you solve from there?
not really
i'm confused
What kind of math do you need help with like decimals or what.
Are you needed with most tipes of math or just some tipes of math

when you set up a proportion 15/300 it can be reduced so 15/300 will become 1/20. 20x20= 400 so 1x20=20.
1/20=?/400
?=20
the answer is 20
your welcome Aj and people of earth

The answer is 20 units because 15/300 = x/400 15/300 is equal to 1/20. 20c20=400.
1x20=20
1/20=x/400
X=20
