Question

6 Last year, all purchases of a certain product were made either online or in a store. If 55 percent of the purchases were made online, what was the ratio of the number of purchases made online to the number of purchases made in a store?

Answer 1

We solve as follows:

*First: We determine the percentage of store purchases:

$100-55=45$

*Second: The ratio is obtained as follows:

$55\colon45=11\colon9$

So, the ratio is 11 to 9 purchases.
