Need help for This question. TIA

Megan, Nora and olivia shared the cost of a rental flat. Megan paid 2/5 of the total amount paid by Nora and Olivia.
The ratio of the amount paid by Nora to the total amount paid by Megan and Olivia was 1:3.

What is the ratio of the rent paid by Megan to Nora to Olivia?

Megan : 2units (x4) = 8units
Nora + Olivia : 5 units (x4) = 20 units
Total : 2 + 5 = 7 units (x4) = 28 units

Nora : 1 unit (x7) = 7 units
Olivia + Megan : 3 units (x7) = 21 units
Total : 1 + 3 = 4 units (x7) = 28 units

Change the total of both to the same multiple, then we have
Megan : Nora + Olivia
(---8---) : (------20------)

Nora : Olivia + Megan
(--7--) : (--------21--------)

therefore, the ratio of
Megan : Nora : Olivia
(---8---) : (--7--): (28 - 8 -7)

which is 8 : 7 : 13 (answer)
