Hiroshi has 4 engines and 18 box cars. find the ratio of engines to box cars. write the ratio as a fraction in simplest form.

So, to write this ratio, you need to write the total engines first, then the boxcars like this: 4 (engines):18 (boxcar). Now we can the ratio as a fraction by changing the: to /: 4:18 becomes 4/18. Now, we can simplify this by dividing the numerator and the denominator by 2. 4 divided by 2 = 2 and 18 divided by 2 = 9. So the simplified version of the ration 4:18 is 2/9. This means for every 2 engines, there are 9 boxcars. Hope this helped!
