Answer 1

Martina would use rac{9}{7} of a bottle of conditioner in a full year.

Step-by-step explanation:

To find out how much conditioner Martina would use in a full year, we can set up a proportion using the given information. She used 3/4 of a bottle in 7/12 of a year. Let x represent the amount of conditioner she would use in a full year.

So we have the proportion: (3/4) / (7/12) = x / 1. To solve for x, we can cross multiply:

3/4 * 12/7 = x * 1

36/28 = x

Simplifying the fraction we get: 9/7 = x

Therefore, Martina would use 9/7 of a bottle of conditioner in a full year.
