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?

Respuesta :

We solve as follows:

*First: We determine the percentage of store purchases:

[tex]100-55=45[/tex]

*Second: The ratio is obtained as follows:

[tex]55\colon45=11\colon9[/tex]
