Question

A supervisor is setting up a display of cereal boxes. The ratio of frosted to unfrosted cereals in the display is 5: 7. Approximately what percent

of the cereal boxes are unfrosted?
A) 40.0%
B) 41.7%
C) 58.3%

Answer 1

The ratio of frosted to unfrosted cereals is 5:7, which means that for every 5 frosted cereal boxes, there are 7 unfrosted cereal boxes.

To determine the percentage of unfrosted cereal boxes in the display, we need to find the fraction of the total number of cereal boxes that are unfrosted. Let's call the total number of cereal boxes "x".

Then, the number of unfrosted cereal boxes would be 7/12 of "x" (since the ratio of unfrosted to total cereal boxes is 7/12).

So, the percentage of unfrosted cereal boxes would be:

(7/12)x * 100%

Simplifying this expression, we get:

(7/12)x * 100% = (58.3%)x

Therefore, the answer is (C) 58.3%.
