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
=)
btw im a 7th grader
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
it is 20
20 since that's what everyone else says
Oh nvm I realized it’s 20! Have a wonderful day everyone 😄✌️ Stay safe btw
Help plsss
Ok pls tell if it’s correct I do public school I want to know.
I can assist with various types of math, including proportions.
Let's break down the problem step by step:
1. First, we are given that the map of Oregon is 15 inches tall from north to south. This is our known measurement.
2. We are also given that Oregon is about 400 miles from west to east and 300 miles from north to south.
3. We need to find out how wide the map is (in inches).
To solve this, we can set up a proportion:
The ratio of inches to miles from north to south is 15/300.
The ratio of inches to miles from west to east is what we need to find (let's call it x/400).
So, we can set up the proportion: 15/300 = x/400.
To solve for x (the width of the map), we can cross-multiply:
15 * 400 = 300 * x.
Now we have:
6000 = 300x.
To isolate x, divide both sides of the equation by 300:
x = 6000/300.
Simplifying this calculation, we find that x = 20.
Therefore, the map is approximately 20 inches wide from west to east.
I hope this explanation helps you understand the process. Let me know if you have any further questions!
