The ratio of two positive integers is 7 to 9. One number is 4 more than the other. What are the two integers?

Let x be one integer and x+4 will be the other. Therefore, X/(X+4) = 7/9 since the ratio of the two numbers is 7/9 (or less than 1) the larger number will be on the bottom. If you cross multiply the ratiOS, you can solve for x. X*9 = (X+4)*7 9X = 7X + 28 2X = 28, so X = 14 and the other number is 18. The ratio of 14 to 18 is 7/9.
