Explanation / Answer

Post one more question to get the remaining two answers. Thanks

5)

Let the number of adults meals sold be x

Ratio of Children/Ratio of Adult Meal = 5/4 (Given)

Number of Children Meal = 20

Substituting the values we get

20/x = 5/4

or x = 16

Combined amount of meals = Kids meal + adult meals = 20 + 16 = 36

6)

Number of Pencils = 34

Sharpened Pencils = 16

Unsharpened Pencils = Number of Pencils - Sharpened Pencils

=> 34 - 16

=> 18 pencils

Ratio of Unsharpened Pencils/ Ratio of Sharpened Pencils

=> 18/16 = 9/8

7)

Let the number of ranch dressing be x

Ratio of Ranch Dressing /Ratio of Caesar Dressing = 8/3 (Given)

Number of ranch dressing = 72

Substituting the values we get

72/x = 8/3

or x = 27

Hence number of caesar dressing is equal to 27
