Answer:

The numbers are 42 and 49

Step-by-step explanation:

Let's make it into a simple equation. Make the ratios into a single variable like this: 6x+7x=91. If you simplify it more you would get 13x=91. From here divide both sides by 13. This will result with x being 7. But the problem wants you to find 6x and 7x. If you multiply 7 with 6 you would have an answer of 42. If you multiply 7 with 7 you get 49. If you want to check add 42 and 49. If you get 91, this means that the answer is correct
