What is the ratio of 24 inches to 5 inches?this is a math question.please help me answer this question.

With the numbers you gave, it is simply 24:5

If it was 25 inches to 5 inches, then you would be simplifying.  The ratio of 25:5 is the same as 5:1.  However, since 5 doesn't go into 24 evenly you can't simplify if the problem is 24 inches to 5 inches.

Also, check to be sure the problem isn't inches and feet instead of both inches.
