Rachel spent 2 1/4 hours practing for her violin solo 5 times last week . How much times did Rachel spend practicing last week?

2.25 * 5 = 11.24 = 11 1/4

or
(9/4)5 = 45/4 = 11 1/4

To determine the total time Rachel spent practicing last week, we need to multiply the time she spent practicing (2 1/4 hours) by the number of times she practiced (5). Since 2 1/4 hours can also be expressed as 9/4 hours, we can calculate the answer as follows:

(9/4 hours) * 5 = (9 * 5) / 4 = 45/4 hours

Thus, Rachel spent a total of 45/4 hours (or 11 1/4 hours) practicing last week.
