Answer:
Hannah received £56 last week
Explanation:
Zoe as a ratio of 3 of the tips that was shared with Hannah. if Zoe received £24 for are share of ratio 3, therefore, 1 share ratio is £24/3 = £8.
Since Hannah has 7 share ratio of the tip, and 1 share ratio is £8, therefore, Hannah will receive £8*7 = £56
Therefore Zoe and Hannah share the total ratio of the tips which is 3+7 = 10.
And the total tips shared is £8*10 = £80
