How can you calculate impressions when given clicks and CTR?

To calculate impressions when you have the number of clicks and the click-through rate (CTR), you can use the formula that represents the relationship between these values. CTR is expressed as a percentage and is the ratio of clicks to impressions.

The formula for CTR is defined as:

CTR = (Clicks / Impressions) * 100

To find impressions, you need to rearrange this formula. Starting from the CTR formula, you can solve for Impressions:

1. Divide both sides of the CTR equation by 100 to convert it from a percentage to a decimal:

CTR / 100 = Clicks / Impressions.

2. Rearranging gives:

Impressions = Clicks / (CTR / 100).

This shows that to find the number of impressions, you divide the number of clicks by the CTR (expressed as a decimal). Hence, multiplying the clicks by 100 and then dividing by the CTR value yields the total impressions.

Thus, the correct choice effectively describes this calculation, demonstrating how to determine total impressions based on clicks and CTR.
