This is quite an unusual scenario...:/ It all hinges on her weekly earnings. If she were to work 40 hours each week at $10 per hour, then she would have sufficient funds. Even if she were a student working part-time for 30 hours at $8 per hour, she would still accumulate enough.
To express (13/15) / (7/10) in its simplest form, follow these steps:
(13/15) / (7/10) = <span>(13/15) * (10/7) = (13 * 2) / (3 * 7) = 26/21 = 1 5/21
</span>
The final answer would be <span>26/21.</span>
