A buffet offers ranch or caesar dressing. The ratio of ranch dressing used to caesar dressing used 8:3 if the buffet uses 72 cases of ranch dressing how many cases of caesar do they use

First we want to find what one unit is equal to:

72 divided by 8 = 9

Then we multiply the single unit of 9 by 3 = 27

The ratio of the ranch dressing to casar dressing in the buffet = 8:3

Number of cases ranch dressings in the buffet = 72

Let us assume the common ratio to be = x

Then

8x = 72

x = 72/8

= 9

So

The number of cases of casar dressing in the buffet = 3 * 9

= 27

So there are 27 cases of casar dressings in the buffet. I hope the procedure is clear enough for you to understand.
