What is the rating if there is a 25% share and 100 HUTs?

To determine the rating based on the given share and HUTs (Households Using Television), the formula to use is:

Rating = Share × HUTs.

In this case, the share is expressed as a percentage, which means it should be converted into a decimal for the calculation. With a 25% share, this is represented as 0.25 in decimal form.

Using the number of HUTs, which is 100, the calculation proceeds as follows:

Rating = 0.25 × 100 = 25.0.

The resulting rating of 25.0 reflects the percentage of the total potential audience that viewed a particular program, when there are 100 HUTs available. Thus, this calculation clearly leads to the understanding that with a 25% share of 100 HUTs, the final rating is 25.0.
