Respuesta :

ANSWER

8 : 3

EXPLANATION

We have that the jar contains 990 beans, 8/11 of which are kidney beans.

The number of kidney beans are:

8 / 11 * 990 = 720

We can find the number of navy beans by subtracting the number of kidney beans from the total number of beans:

990 - 720 = 270

Therefore, the ratio of kidney beans to navy beans is:

720 : 270

In lowest terms:

8 : 3

That is the answer.
